Product Overview
High-quality enzyme products. Well-defined strains can be also provided for our clients to manufacture fermented products in a cost-effective way.
Features
Ready-to-use product, accelerating research progress, enhancing application performance.
Synonyms
D-aspartate transaminase; D-alanine aminotransferase; D-aspartic aminotransferase; D-alanine-D-glutamate transaminase; D-alanine transaminase; D-amino acid aminotransferase
Function
A pyridoxal-phosphate protein. The enzyme from thermophilic Bacillus species acts on many D-amino acids with D-alanine and D-2-aminobutyrate as the best amino donors. It can similarly use any of several 2-oxo acids as amino acceptor, with 2-oxoglutarate and 2-oxobutyrate among the best. The enzyme from some other sources has a broader specificity.

Unit Definition
One Unit of D-glutamate-pyruvate transaminase (D-GPT) is defined as the amount of enzyme required to produce one μmole of NAD+ from NADH.
Reaction
D-alanine + 2-oxoglutarate = pyruvate + D-glutamate
