General Comments
FAAL32-Pks13 polyketide synthase catalyzes the condensation reaction, which produces α-alkyl β-ketoacids, direct precursors of mycolic acids. This function is carried out by its thioesterase-like domain as a unique mechanism to transfer polyketide synthase products in mycobacteria, hence the focus on this as a drug target [2].
