Crystal Structure of the Priming beta-Ketosynthase from the R1128 Polyketide Biosynthetic PathwayCrystal Structure of the Priming beta-Ketosynthase from the R1128 Polyketide Biosynthetic Pathway
Structural highlights
1mzj is a 2 chain structure with sequence from Streptomyces sp. R1128. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
FABH_STRLI Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Catalyzes the first condensation reaction which initiates fatty acid synthesis and may therefore play a role in governing the total rate of fatty acid production. Possesses both acetoacetyl-ACP synthase and acetyl transacylase activities. Has some substrate preference for butyryl-CoA and can tolerate branched substrates. Can also prime acyl-CoA. Its substrate specificity determines the biosynthesis of branched-chain and/or straight-chain of fatty acids. Involved in the biosynthesis of R1128 polyketide.[1]
