|
Alternative Name(s) |

Reaction catalysed |
- 8 (S)-methylmalonyl-CoA + palmitoyl-[(hydroxy)phthioceranic acid synthase] + 16 NADPH <=> 8 CoA + C(40)-phthioceranyl-[(hydroxy)phthioceranic acid synthase] + 16 NADP(+) + 8 CO(2) + 8 H(2)O
- 7 (S)-methylmalonyl-CoA + palmitoyl-[(hydroxy)phthioceranic acid synthase] + 14 NADPH <=> 7 CoA + C(37)-phthioceranyl-[(hydroxy)phthioceranic acid synthase] + 14 NADP(+) + 7 CO(2) + 7 H(2)O

Comment(s) |
- This mycobacterial polyketide enzyme produces the hepta- and octa-
methylated fatty acids known as phthioceranic acids, and presumably
their hydroxylated versions.
- Formation of hepta- and octamethylated products depends on whether
the enzyme incorporates seven or eight methylmalonyl-CoA extender
units, respectively.
- Formation of hydroxylated products may result from the enzyme
skipping the dehydratase (DH) and enoylreductase (ER) domains during
the first cycle of condensation.
