Molecular cloning of the aspartate 4-decarboxylase gene from Pseudomonas sp. ATCC 19121 and characterization of the bifunctional recombinant enzyme
Abstract l-Aspartate 4-decarboxylase (Asd) is a major enzyme used in the industrial production of l-alanine. Its gene was cloned from Pseudomonas sp. ATCC 19121 and characterized in the present study. The 1,593-bp asd encodes a protein with a molecular mass of 59,243 Da. The Asd from this Pseudomona...

520 | |a Abstract l-Aspartate 4-decarboxylase (Asd) is a major enzyme used in the industrial production of l-alanine. Its gene was cloned from Pseudomonas sp. ATCC 19121 and characterized in the present study. The 1,593-bp asd encodes a protein with a molecular mass of 59,243 Da. The Asd from this Pseudomonas strain was considerably homologous to other Asds and aminotransferases, and has evolved independently of these enzymes from gram-positive microbes. Productivity rate of the C-terminal His-tagged fusion Asd was at 33 mg/l of Escherichia coli transformant culture. The kinetic parameters Km and Vmax of the fusion protein were 11.50 mM and 0.11 mM/min, respectively. Gel filtration analysis demonstrated that Asd is a dodecamer at pH 5.0 while 4.4 % of the recombinant protein dissociated into dimer when the pH was increased to 7.0. Asd exhibited its maximum activity at pH 5.0 and specific activity of 280 U/mg, and remained stable over a broad range of pH. The optimum temperature for Asd reaction was 45 °C, and 92 % of the activity remained when the enzyme was incubated at 40 °C for 40 min. This enzyme did not have any preferred divalent cation for catalysis. The recombinant Asd also exhibited aminotransferase activity when d,l-Asp, l-Glu, l-Gln, and l-Ala were utilized as substrates. However, the decarboxylation activity of l-aspartate was 2,477 times higher than its aminotransferase activity. The present study is the first investigation on the important biochemical properties of the purified recombinant Asd. | ||

ATCC 19121 and characterization of the bifunctional recombinant enzyme 2006 Text txt rdacontent Computermedien c rdamedia Online-Ressource cr rdacarrier © Springer-Verlag 2006 Abstract l-Aspartate 4-decarboxylase (Asd) is a major enzyme used in the industrial production of l-alanine. Its gene was cloned from Pseudomonas sp. ATCC 19121 and characterized in the present study. The 1,593-bp asd encodes a protein with a molecular mass of 59,243 Da. The Asd from this Pseudomonas strain was considerably homologous to other Asds and aminotransferases, and has evolved independently of these enzymes from gram-positive microbes. Productivity rate of the C-terminal His-tagged fusion Asd was at 33 mg/l of Escherichia coli transformant culture. The kinetic parameters Km and Vmax of the fusion protein were 11.50 mM and 0.11 mM/min, respectively. Gel filtration analysis demonstrated that Asd is a dodecamer at pH 5.0 while 4.4 % of the recombinant protein dissociated into dimer when the pH was increased to 7.0. Asd exhibited its maximum activity at pH 5.0 and specific activity of 280 U/mg, and remained stable over a broad range of pH. The optimum temperature for Asd reaction was 45 °C, and 92 % of the activity remained when the enzyme was incubated at 40 °C for 40 min. This enzyme did not have any preferred divalent cation for catalysis. The recombinant Asd also exhibited aminotransferase activity when d,l-Asp, l-Glu, l-Gln, and l-Ala were utilized as substrates. However, the decarboxylation activity of l-aspartate was 2,477 times higher than its aminotransferase activity. The present study is the first investigation on the important biochemical properties of the purified recombinant Asd.

Its gene was cloned from Pseudomonas sp. ATCC 19121 and characterized in the present study. The 1,593-bp asd encodes a protein with a molecular mass of 59,243 Da. The Asd from this Pseudomonas strain was considerably homologous to other Asds and aminotransferases, and has evolved independently of these enzymes from gram-positive microbes. Productivity rate of the C-terminal His-tagged fusion Asd was at 33 mg/l of Escherichia coli transformant culture. The kinetic parameters Km and Vmax of the fusion protein were 11.50 mM and 0.11 mM/min, respectively. Gel filtration analysis demonstrated that Asd is a dodecamer at pH 5.0 while 4.4 % of the recombinant protein dissociated into dimer when the pH was increased to 7.0. Asd exhibited its maximum activity at pH 5.0 and specific activity of 280 U/mg, and remained stable over a broad range of pH. The optimum temperature for Asd reaction was 45 °C, and 92 % of the activity remained when the enzyme was incubated at 40 °C for 40 min. This enzyme did not have any preferred divalent cation for catalysis. The recombinant Asd also exhibited aminotransferase activity when d,l-Asp, l-Glu, l-Gln, and l-Ala were utilized as substrates. However, the decarboxylation activity of l-aspartate was 2,477 times higher than its aminotransferase activity. The present study is the first investigation on the important biochemical properties of the purified recombinant Asd.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">High Performance Liquid Chromatography</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pseudomonas</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Alcaligenes Faecalis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cunninghamella Elegans</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Putative Aminotransferase</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lee, Chia-Yin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied microbiology and biotechnology</subfield><subfield code="d">Berlin : Springer, 1975</subfield><subfield code="g">73(2006), 2 vom: 08.

Molecular cloning of the aspartate 4-decarboxylase gene from Pseudomonas sp. ATCC 19121 and characterization of the bifunctional recombinant enzyme |
abstract |
Abstract l-Aspartate 4-decarboxylase (Asd) is a major enzyme used in the industrial production of l-alanine. Its gene was cloned from Pseudomonas sp. ATCC 19121 and characterized in the present study. The 1,593-bp asd encodes a protein with a molecular mass of 59,243 Da. The Asd from this Pseudomonas strain was considerably homologous to other Asds and aminotransferases, and has evolved independently of these enzymes from gram-positive microbes. Productivity rate of the C-terminal His-tagged fusion Asd was at 33 mg/l of Escherichia coli transformant culture. The kinetic parameters Km and Vmax of the fusion protein were 11.50 mM and 0.11 mM/min, respectively. Gel filtration analysis demonstrated that Asd is a dodecamer at pH 5.0 while 4.4 % of the recombinant protein dissociated into dimer when the pH was increased to 7.0. Asd exhibited its maximum activity at pH 5.0 and specific activity of 280 U/mg, and remained stable over a broad range of pH. The optimum temperature for Asd reaction was 45 °C, and 92 % of the activity remained when the enzyme was incubated at 40 °C for 40 min. This enzyme did not have any preferred divalent cation for catalysis. The recombinant Asd also exhibited aminotransferase activity when d,l-Asp, l-Glu, l-Gln, and l-Ala were utilized as substrates. However, the decarboxylation activity of l-aspartate was 2,477 times higher than its aminotransferase activity. The present study is the first investigation on the important biochemical properties of the purified recombinant Asd. © Springer-Verlag 2006 |
