[https://www.uniprot.org/uniprot/KASA_MYCTU KASA_MYCTU] Part of the mycobacterial fatty acid elongation system FAS-II, which is involved in mycolic acid biosynthesis. Catalyzes the elongation of long chain acyl-ACP substrates by the addition of two carbons from malonyl-ACP to an acyl acceptor (PubMed:11600501, PubMed:12023885, PubMed:12464486, PubMed:16873379, PubMed:22017312, PubMed:24108128). Involved in the initial extension of the mycolate chain and forms monounsaturated fatty acids that averaged 40 carbons in length (PubMed:12464486).<ref>PMID:11600501</ref> <ref>PMID:12023885</ref> <ref>PMID:12464486</ref> <ref>PMID:16873379</ref> <ref>PMID:22017312</ref> <ref>PMID:24108128</ref>

== Publication Abstract from PubMed ==
 +
Published Mycobacterium tuberculosis beta-ketoacyl-ACP synthase KasA inhibitors lack sufficient potency and/or pharmacokinetic properties. A structure-based approach was used to optimize existing KasA inhibitor DG167. This afforded indazole JSF-3285 with a 30-fold increase in mouse plasma exposure. Biochemical, genetic, and X-ray studies confirmed JSF-3285 targets KasA. JSF-3285 offers substantial activity in an acute mouse model of infection and in the corresponding chronic infection model, with efficacious reductions in colony-forming units at doses as low as 5 mg/kg once daily orally and improvement of the efficacy of front-line drugs isoniazid or rifampicin. JSF-3285 is a promising preclinical candidate for tuberculosis.
