KEGG ENZYME: 2.5.1.113

ENZYME: 2.5.1.113

Entry

EC 2.5.1.113                Enzyme

Name

[CysO sulfur-carrier protein]-thiocarboxylate-dependent cysteine synthase;
CysM

Class

Transferases;
Transferring alkyl or aryl groups, other than methyl groups;
Transferring alkyl or aryl groups, other than methyl groups (only sub-subclass identified to date)

Sysname

O-phospho-L-serine:thiocarboxylated [CysO sulfur-carrier protein] 2-amino-2-carboxyethyltransferase

Reaction(IUBMB)

O-phospho-L-serine + [CysO sulfur-carrier protein]-Gly-NH-CH2-C(O)SH = [CysO sulfur-carrier protein]-Gly-NH-CH2-C(O)-S-L-cysteine + phosphate [RN:R10610]

Reaction(KEGG)

R10610

Substrate

O-phospho-L-serine [CPD:C01005];
[CysO sulfur-carrier protein]-Gly-NH-CH2-C(O)SH [CPD:C15814]

Product

[CysO sulfur-carrier protein]-Gly-NH-CH2-C(O)-S-L-cysteine [CPD:C20729];
phosphate [CPD:C00009]

Comment

A pyridoxal-phosphate protein. The enzyme participates in an alternative pathway for L-cysteine biosynthesis that involves a protein-bound thiocarboxylate as the sulfide donor. The enzyme from the bacterium Mycobacterium tuberculosis also has very low activity with O3-acetyl-L-serine (cf. EC 2.5.1.65, O-phosphoserine sulfhydrylase).

History

EC 2.5.1.113 created 2013

Orthology
