KEGG ENZYME: 2.3.1.165

ENZYME: 2.3.1.165

Entry

EC 2.3.1.165 Enzyme

Name

6-methylsalicylic-acid synthase;
MSAS;
6-methylsalicylic acid synthase

Class

Transferases;
Acyltransferases;
Transferring groups other than aminoacyl groups

Sysname

acyl-CoA:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl-reducing, thioester-hydrolysing and cyclizing)

Reaction(IUBMB)

acetyl-CoA + 3 malonyl-CoA + NADPH + H+ = 6-methylsalicylate + 4 CoA + 3 CO2 + NADP+ + H2O [RN:R07253]

Reaction(KEGG)

R07253

Substrate

acetyl-CoA [CPD:C00024];
malonyl-CoA [CPD:C00083];
NADPH [CPD:C00005];
H+ [CPD:C00080]

Product

6-methylsalicylate [CPD:C02657];
CoA [CPD:C00010];
CO2 [CPD:C00011];
NADP+ [CPD:C00006];
H2O [CPD:C00001]

Comment

A multienzyme complex with a 4'-phosphopantetheine prosthetic group on the acyl carrier protein. It has a similar sequence to vertebrate type I fatty acid synthase. Acetoacetyl-CoA can also act as a starter molecule.
