Comments

Comment Type Description
Catalytic Activity L-isoleucine + 2-oxoglutarate = (S)-3-methyl- 2-oxopentanoate + L-glutamate.
Catalytic Activity L-leucine + 2-oxoglutarate = 4-methyl-2- oxopentanoate + L-glutamate.
Catalytic Activity L-valine + 2-oxoglutarate = 3-methyl-2- oxobutanoate + L-glutamate.
Cofactor Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
Developmental Stage Highly expressed during logarithmic phase of growth. Down-regulated during the stationary phase.
Function Involved in the biosynthesis of the branched chain amino acids leucine, isoleucine, and valine. Catalyzes the formation of methionine from 2-keto-4-methylthiobutyrate (KMTB) in the methionine salvage pathway primarily using branched chain amino acids (leucine, isoleucine, and valine) as the amino donors. Appears to be involved in the regulation of the transition from G1 to S phase in the cell cycle. High copy suppressor of a temperature-sensitive mutation in the ABC transporter, ATM1
