[https://www.uniprot.org/uniprot/INLPD_MYCTU INLPD_MYCTU] Involved in the biosynthesis of a unique class of isonitrile lipopeptides (INLPs) that seem to function as virulence factors in M.tuberculosis and to play a role in metal acquisition (PubMed:28634299). Catalyzes a Michael addition of glycine to the beta-position of an alpha,beta-unsaturated fatty acyl-[ACP], producing a (3R)-3-[(carboxymethyl)amino]fatty acid. Acts on the (2E)-decenoyl moiety loaded on the acyl-carrier protein (ACP) Rv0100, forming the product (3R)-3-[(carboxymethyl)amino]decanoate released from the ACP (By similarity). Displays thioesterase activity with a preference for long chain fatty acyl groups; in vitro, cleaves the thioester linkage of palmitoyl-CoA, stearoyl-CoA, lauroyl-CoA and hexanoyl-CoA (PubMed:17524985). Contains low levels of trans-enoyl hydratase activity (PubMed:19136596).[UniProtKB:B2HKM2]<ref>PMID:17524985</ref> <ref>PMID:19136596</ref> <ref>PMID:28634299</ref>

== Publication Abstract from PubMed ==
 +
The crystal structure of Rv0098, a long-chain fatty acyl-CoA thioesterase from Mycobacterium tuberculosis with bound dodecanoic acid at the active site provided insights into the mode of substrate binding but did not reveal the structural basis of substrate specificities of varying chain length. Molecular dynamics studies demonstrated that certain residues of the substrate binding tunnel are flexible and thus modulate the length of the tunnel. The flexibility of the loop at the base of the tunnel was also found to be important for determining the length of the tunnel for accommodating appropriate substrates. A combination of crystallographic and molecular dynamics studies thus explained the structural basis of accommodating long chain substrates by Rv0098 of M. tuberculosis.
