Facile Alkaline Lysis of Escherichia coli Cells in High-Throughput Mode for Screening Enzyme Mutants: Arylsulfatase as an Example
Facile alkaline lysis of Escherichia coli cells in high-throughput (HTP) mode for screening enzyme mutants was tested with Pseudomonas aeruginosa arylsulfatase (PAAS). The alkaline lysis buffer was 1.0 M Tris-HCl at pH 9.0 plus 0.1 % Tween-20 and 2.0 mM 4-aminobenzamidine, mixed with cell suspension...

520 | |a Facile alkaline lysis of Escherichia coli cells in high-throughput (HTP) mode for screening enzyme mutants was tested with Pseudomonas aeruginosa arylsulfatase (PAAS). The alkaline lysis buffer was 1.0 M Tris-HCl at pH 9.0 plus 0.1 % Tween-20 and 2.0 mM 4-aminobenzamidine, mixed with cell suspension at 8:1 to 12:1 ratio for continuous agitation of mixtures in 96-well plates under room temperature; enzymatic activity in lysates was measured with 96-well microplate. PAAS activity tolerated final 0.1 % Tween-20. Individual clones were amplified for 12 h in 0.50 mL TB medium with 48-well plates to enhance the repeatability of induced expression. During continuous agitation of the mixture of cells and the lysis buffer, PAAS activities in lysates were steady from 3 to 9 h and comparable to sonication treatment but better than freezing-thawing. Coefficients of variation of activities of PAAS/mutants in lysates after treatment for 7 h reached ∼22 %. The mutant M72Q had specific activity 2-fold of G138S. By HTP lysis of cells, M72Q was recognized as a positive mutant over G138S with the area under the curve of 0.873. Therefore, for enzymes tolerating concentrated alkaline buffers, the proposed alkaline lysis approach may be generally applicable for HTP lysis of host cells during directed evolution. | ||

PAAS activity tolerated final 0.1 % Tween-20. Individual clones were amplified for 12 h in 0.50 mL TB medium with 48-well plates to enhance the repeatability of induced expression. During continuous agitation of the mixture of cells and the lysis buffer, PAAS activities in lysates were steady from 3 to 9 h and comparable to sonication treatment but better than freezing-thawing. Coefficients of variation of activities of PAAS/mutants in lysates after treatment for 7 h reached ∼22 %. The mutant M72Q had specific activity 2-fold of G138S. By HTP lysis of cells, M72Q was recognized as a positive mutant over G138S with the area under the curve of 0.873.

Facile Alkaline Lysis of Escherichia coli Cells in High-Throughput Mode for Screening Enzyme Mutants: Arylsulfatase as an Example |
abstract |
Facile alkaline lysis of Escherichia coli cells in high-throughput (HTP) mode for screening enzyme mutants was tested with Pseudomonas aeruginosa arylsulfatase (PAAS). The alkaline lysis buffer was 1.0 M Tris-HCl at pH 9.0 plus 0.1 % Tween-20 and 2.0 mM 4-aminobenzamidine, mixed with cell suspension at 8:1 to 12:1 ratio for continuous agitation of mixtures in 96-well plates under room temperature; enzymatic activity in lysates was measured with 96-well microplate. PAAS activity tolerated final 0.1 % Tween-20. Individual clones were amplified for 12 h in 0.50 mL TB medium with 48-well plates to enhance the repeatability of induced expression. During continuous agitation of the mixture of cells and the lysis buffer, PAAS activities in lysates were steady from 3 to 9 h and comparable to sonication treatment but better than freezing-thawing. Coefficients of variation of activities of PAAS/mutants in lysates after treatment for 7 h reached ∼22 %. The mutant M72Q had specific activity 2-fold of G138S. By HTP lysis of cells, M72Q was recognized as a positive mutant over G138S with the area under the curve of 0.873. Therefore, for enzymes tolerating concentrated alkaline buffers, the proposed alkaline lysis approach may be generally applicable for HTP lysis of host cells during directed evolution. |

Coefficients of variation of activities of PAAS/mutants in lysates after treatment for 7 h reached ∼22 %. The mutant M72Q had specific activity 2-fold of G138S. By HTP lysis of cells, M72Q was recognized as a positive mutant over G138S with the area under the curve of 0.873. Therefore, for enzymes tolerating concentrated alkaline buffers, the proposed alkaline lysis approach may be generally applicable for HTP lysis of host cells during directed evolution.</subfield></datafield><datafield tag="540" ind1=" " ind2=" "><subfield code="a">Nutzungsrecht: © Springer Science+Business Media New York 2016</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Positive mutants</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biochemistry, general</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Directed evolution</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Chemistry</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">High-throughput screening</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pseudomonas aeruginosa arylsulfatase</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alkaline lysis</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biotechnology</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Xiaolan</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Yuwei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Hongbo</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pu, Jun</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhan, Chang-guo</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liao, Fei</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied biochemistry and biotechnology / A</subfield><subfield code="d">New York, NY : Springer, 1994</subfield><subfield code="g">179(2016), 4, Seite 545-557</subfield><subfield code="w">(DE-627)182278573</subfield><subfield code="w">(DE-600)1193054-8</subfield><subfield code="w">(DE-576)043085105</subfield><subfield code="x">0273-2289</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:179</subfield><subfield code="g">year:2016</subfield><subfield code="g">number:4</subfield><subfield code="g">pages:545-557</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1007/s12010-016-2012-0</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://www.ncbi.nlm.nih.gov/pubmed/26899233</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://search.proquest.com/docview/1799328556</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-CHE</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-DE-84</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4012</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">42.00</subfield><subfield code="q">AVZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">179</subfield><subfield code="j">2016</subfield><subfield code="e">4</subfield><subfield code="h">545-557</subfield></datafield></record></collection>
