EC number
Keyword
  • 5-methyl-naphthoic acid
Note
  • This ORF acts as a chain elongation and cyclization (CEC) domain and is required for the additional two rounds of chain extension to form the 5-methyl naphthoate moiety.
Note (GenBank)
  • thioesterase superfamily protein

comment
[PMID: 18635006](2008)
Azinomycin B生合成遺伝子クラスターの報告。

aziG: Thioesterase

AziF, AziG, AziH1, AziH2, AziH3 の機能は、azinomycin B生合成経路に割り当てることができなかった。
機能予測は配列解析から。

[PMID: 26731610](2016)
予想と異なりPKS(AziB)だけでは5-methyl naphthoate部分を形成することができず、thioesterase(AziG)が追加２ラウンドの鎖伸長と環化を担う。よってAziGは、chain elongation and cyclization (CEC) domain として働く。
