RifR
[Rifam_00540]type II thioesterase

RifRは、acyl-CoAsよりもacyl carrier domainのphosphopantetheinyl armからのacyl unitsを加水分解する(Steady-state kinetics)。
helical lidの運動が、RifR active siteへの基質のアクセスを調節する(立体構造解析)。

RifRがCoA基質よりACP基質への反応を好むことは、type II thioesteraseがcarrier domainsから異常unitsを除くようなhousekeeping functionsをすると考えられていることに一致する。

Thioesterase

対照実験として。
MonAXはdiketide-SNACを加水分解したが、polyether-SNACを加水分解しなかった。
よって、polyether鎖の放出には関与しない。
