SCC Gene Description

Gene name BCAT4
AGI ID AT3G19710
Gene length 354
Uniprot ID Q9LE06
Protein Name Methionine aminotransferase BCAT4
Synonym MMB12_16
EC number EC 2.6.1.88
Entrez Gene 821508
Refseq mrna NM_112861
Refseq protein NP_188605
Function Recombinant BCAT4 showed high efficiency with Met and its derivatives and the corresponding 2-oxo acids suggesting its participation in the chain elongation pathway of Met-derived GSL biosynthesis. This was substantiated by in vivo analysis of two BCAT4 T-DNA knockout mutants in which Met-derived aliphatic GSL accumulation is reduced by nearly 50% (Schuster et al. 2006)
Group GSL side chain elongation
