Sysname
malonyl-CoA C-acyl transferase (1,3,6,8-tetrahydroxynaphthalene-forming)
Reaction(IUBMB)
5 malonyl-CoA = 1,3,6,8-tetrahydroxynaphthalene + 5 CoA + 5 CO2 + H2O [RN:
R10965 ]
Reaction(KEGG)
Substrate
Product
Comment
Isolated from the fungus Colletotrichum lagenarium [1], and the bacteria Streptomyces coelicolor [2,3] and Streptomyces peucetius [4]. It only uses malonyl-CoA, without invovement of acetyl-CoA.
