Branching out : The substrate specificity profiles for a range of ketosynthase (KS) domains from trans ‐AT PKSs are reported. Evidence is provided that a sterically demanding amino acid residue adjacent to the active‐site Cys residue confers specificity towards non‐β‐methyl‐branched substrates (see scheme).
