The protein

Catalyzed reaction/ biological activity

• BacG catalyzes the conjugate addition of hydride at the C4 olefinic terminus using NADH to yield the cyclohexenol- containing tetrahydro-4-hydroxyphenylpyruvate [Pubmed|20052993]
• stereoselective reduction of dihydro-hydroxyphenylpyruvate (H2HPP) to tetrahydro-hydroxyphenylpyruvate (H4HPP), NADPH-dependent reductase that facilitates the conjugate addition of a hydride at the C(4) olefin terminus of H2HPP [Pubmed|23519407]

Protein family

• short-chain dehydrogenases/reductases (SDR) family (according to Swiss-Prot)

[SW|Cofactors]

• NADPH [Pubmed|23519407]
