Crystal structure of accD5 (Rv3280), an acyl-CoA carboxylase beta- subunit from Mycobacterium tuberculosis
Structural highlights
FunctionACCD5_MYCTU Component of a biotin-dependent acyl-CoA carboxylase complex. This subunit transfers the CO2 from carboxybiotin to the CoA ester substrate (PubMed:16354663, PubMed:16385038, PubMed:28222482). When associated with the alpha3 subunit AccA3, is involved in the carboxylation of acetyl-CoA and propionyl-CoA, with a preference for propionyl-CoA (PubMed:16354663, PubMed:16385038, PubMed:28222482). Is also required for the activity of the long-chain acyl-CoA carboxylase (LCC) complex (PubMed:28222482).[1] [2] [3] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedMycobacterium tuberculosis contains multiple versions of the accA and accD genes that encode the alpha- and beta-subunits of at least three distinct multi-functional acyl-CoA carboxylase complexes. Because of its proposed involvement in pathogenic M. tuberculosis survival, the high-resolution crystal structure of the beta-subunit gene accD5 product has been determined and reveals a hexameric 356 kDa complex. Analysis of the active site properties of AccD5 and homology models of the other five M. tuberculosis AccD homologues reveals unexpected differences in their surface composition, providing a molecular rational key for a sorting mechanism governing correct acyl-CoA carboxylase holo complex assembly in M. tuberculosis.
