PksA domain structure, from N- to C-terminus including the starter unit: acylcarrier protein transacylase (SAT), beta-ketoacyl synthase (KS), malonyl-CoA: acyl-carrier protein transacylase (MAT), product template (PT), acyl-carrier protein (ACP), and thioesterase/Claisen cyclase (TE/CLC)
additional information
domain architecture, the enzyme shows an alpha/beta-hydrolase fold in the catalytic closed form with a distinct hydrophobic substrate-binding chamber involving the PksA thioesterase/Claisen cyclase residues Ser1937, His2088, and Asp1964, which constitute the catalytic triad conserved in the alpha/beta-hydrolase family, detailed overview
