Enzymes

General function:
Amino acid transport and metabolism
Specific function:
Catalyzes the first reaction in the catabolism of the essential branched chain amino acids leucine, isoleucine, and valine. May also function as a transporter of branched chain alpha-keto acids (By similarity).
Gene Name:
BCAT2
Uniprot ID:
Q5EA40
Molecular weight:

Reactions
L-Isoleucine + Oxoglutaric acid → 3-Methyl-2-oxovaleric acid + L-Glutamic aciddetails
General function:
Energy production and conversion
Specific function:
The branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO(2). It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3).
