The following text describes a protein:
Function:
Nonribosomal peptide synthetase (NRPS) 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. Catalyzes the final step in the pathway, i.e. the condensation of a (3R)-3-isocyanyl-fatty acyl-[ACP] to both amino groups of a lysine, producing isonitrile lipopeptides (By similarity).
Domain:
Contains 7 domains: 2 C (condensation) domains, 2 A (adenylation) domains, 2 T (thiolation) domains, and one R (reduction) domain at its C-terminus. The first T domain likely acts as a lyine-specific peptidyl-carrier protein, and carries a lyine residue that is transferred to it by the first A domain. The C domain catalyzes the condensation of two isonitrile-containing moieties to both amino groups of the lysine bound to the T domain, a rare activity in nonribosomal peptide biosynthesis. Finally, the R domain catalyzes a four-electron thioester reduction, releasing the product from the NRPS and forming a terminal alcohol product.
