== Publication Abstract from PubMed ==
In Mycobacterium tuberculosis (Mtb) the carboxylation of acetyl-CoA to produce malonyl-CoA, a building block in long chain fatty acid biosynthesis, is catalyzed by two enzymes working sequentially: a biotin carboxylase (AccA), and a carboxyltransferase (AccD). While the exact roles of the three different biotin carboxylases (AccA1-3) and the six carboxyltransferases (AccD1-6) in Mtb are still not clear, AccD6 in complex with AccA3 can synthesize malonyl-CoA from acetyl-CoA. A series of ten herbicides that target plant acetyl-CoA carboxylases (ACC) were tested for inhibition of AccD6 and for whole-cell activity against Mtb. From the tested herbicides, haloxyfop, an arylophenoxypropionate, showed in vitro inhibition of Mtb AccD6, with an IC50 = 21.4 +/- 1 muM. Here, we report the crystal structures of Mtb AccD6 in the apo form (3.0 A) and in complex with haloxyfop-R (2.3 A). The structure of Mtb AccD6 in complex with haloxyfop-R shows two molecules of the inhibitor bound on each AccD6 subunit. These results represent the potential for developing novel therapeutics for tuberculosis based on herbicides with low human toxicity.

Function

ACCD6_MYCTU Component of a biotin-dependent acyl-CoA carboxylase complex. This subunit transfers the CO2 from carboxybiotin to the CoA ester substrate (PubMed:17114269). When associated with the alpha3 subunit AccA3, is involved in the carboxylation of acetyl-CoA and propionyl-CoA, with a preference for acetyl-CoA (PubMed:17114269).[1]
