In enzymology, a homoserine O-succinyltransferase (EC 2.3.1.46) is an enzyme that catalyzes the chemical reaction
- succinyl-CoA + L-homoserine CoA + O-succinyl-L-homoserine
Thus, the two substrates of this enzyme are succinyl-CoA and L-homoserine, whereas its two products are CoA and O-succinyl-L-homoserine.
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is succinyl-CoA:L-homoserine O-succinyltransferase. Other names in common use include homoserine O-transsuccinylase, and homoserine succinyltransferase. This enzyme participates in methionine metabolism and sulfur metabolism.
Structural studies
[edit]As of late 2016, three structures have been solved for this class of enzymes, with PDB accession codes 2GHR, 2H2W, and 2VDJ.
