Originated in SF 1866936
Examples of multistep polyketide biosynthetic processes. To do: check that none of these happen in a concerted process (very unlikely).
Three malonyl transfers and three decarboxylations
- benzophenone synthase activity (GO:0047181), EC:2.3.1.151
- acridone synthase activity (GO:0050635), EC:2.3.1.159
Three malonyl transfers and four decarboxylations
- naringenin-chalcone synthase activity (GO:0016210), EC:2.3.1.74
- 6'-deoxychalcone synthase activity (GO:0033808), EC:2.3.1.170
- pinosylvin synthase activity (GO:0050198), EC:2.3.1.146
- trihydroxystilbene synthase activity (GO:0050350), EC:2.3.1.95
- phloroisovalerophenone synthase activity (GO:0050634), EC:2.3.1.156
- 6-methylsalicylic acid sytnhase activity (GO:0050641), EC:2.3.1.165
These are actually multistep processes involving three malonyl transfers and four decarboxylations. The overall details are described in PMID: 11959984. The reaction specifics for GO:0016210 are in PMID: 10653632, which describes how it's a succession of malonyl-CoA decarboxylations followed by transfer of the acetyl group to the polyketide chain.
Six malonyl transfers
- erythronolide synthase activity (GO:0047879), EC:2.3.1.94
Eight malonyl transfers
- lovastatin nonaketide synthase activity (GO:0050637), EC:2.3.1.161
the clue here is in the synonym: acyl-CoA:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl- and enoyl-reducing, thioester-hydrolysing)
Uncounted
- mycocerosate synthase activity (GO:0050111), EC:2.3.1.111 [0 gene products]
- biphenyl synthase activity (GO:0033815), EC:2.3.1.177 [0 gene products]
- icosanoyl-CoA synthase activity (GO:0033807), EC:2.3.1.119 [0 gene products]
