Function
function
Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine.
Catalytic activity
- acetyl-CoA + L-homoserine = CoA + O-acetyl-L-homoserine
Pathway
Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; O-acetyl-L-homoserine from L-homoserine: step 1/1.
