Polyphenol Oxidase from Bean Sprouts (Glycine max L.)
: Polyphenol oxidase (PPO) was purified and characterized from bean sprouts by ammonium sulfate precipitation, DEAE-Toyopearl 650M, CM-Toyopearl 650M, SuperQ-Toyopearl 650S and QAE-Toyopearl 550C column chromatographies. Substrate staining of the crude extract on electrophoresis showed the presence...

Polyphenol Oxidase from Bean Sprouts (Glycine max L.) |
abstract |
: Polyphenol oxidase (PPO) was purified and characterized from bean sprouts by ammonium sulfate precipitation, DEAE-Toyopearl 650M, CM-Toyopearl 650M, SuperQ-Toyopearl 650S and QAE-Toyopearl 550C column chromatographies. Substrate staining of the crude extract on electrophoresis showed the presence of 2 isozymic forms of this enzyme. The molecular weight of the purified enzyme was estimated to be about 54 kDa. The optimum pH was 9.0 and optimum temperature 40 °C. Heat inactivation occurred about 30 °C. PPO showed activity to catechol, pyrogallol and dopamine. These compounds such as ascorbic acid, L-cysteine, 2-mercaptoethanol, and glutathione used was the effective inhibitor. Enzyme activity was maintained for 7 d at 4 °C but suddenly decreased after 8 d. |

Substrate staining of the crude extract on electrophoresis showed the presence of 2 isozymic forms of this enzyme. The molecular weight of the purified enzyme was estimated to be about 54 kDa. The optimum pH was 9.0 and optimum temperature 40 °C. Heat inactivation occurred about 30 °C. PPO showed activity to catechol, pyrogallol and dopamine. These compounds such as ascorbic acid, L-cysteine, 2-mercaptoethanol, and glutathione used was the effective inhibitor. Enzyme activity was maintained for 7 d at 4 °C but suddenly decreased after 8 d.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2006</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2006||||||||||</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">polyphenol oxidase</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Suzuki, N.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">Journal of food science</subfield><subfield code="d">Chicago, Ill. : Inst., 1990</subfield><subfield code="g">68(2003), 1, Seite 0</subfield><subfield code="w">(DE-627)NLEJ243926316</subfield><subfield code="w">(DE-600)2006705-7</subfield><subfield code="x">1750-3841</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:68</subfield><subfield code="g">year:2003</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1111/j.1365-2621.2003.tb14107.x</subfield><subfield code="q">text/html</subfield><subfield code="x">Verlag</subfield><subfield code="z">Deutschlandweit zugänglich</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-DJB</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">68</subfield><subfield code="j">2003</subfield><subfield code="e">1</subfield><subfield code="h">0</subfield></datafield></record></collection>
