[https://www.uniprot.org/uniprot/BIRA_MYCTU BIRA_MYCTU] Catalyzes the transfer of biotin onto a conserved lysine residue of the biotin carboxyl carrier protein (BCCP) domain of acetyl-CoA carboxylase and converts it to active holo-BCCP (PubMed:18509457, PubMed:24723382). Forms an acyl-adenylate intermediate (PubMed:18509457, PubMed:24723382). Cannot use GTP or desthiobiotin (PubMed:18509457).<ref>PMID:18509457</ref> <ref>PMID:24723382</ref>

Mycobacterium tuberculosis (Mtb) responsible for both latent and symptomatic tuberculosis (TB) remains the second leading cause of mortality among infectious diseases worldwide. Mycobacterial biotin protein ligase (MtBPL) is an essential enzyme in Mtb and regulates lipid metabolism through the post-translational biotinylation of acyl coenzyme A carboxylases. We report the synthesis and evaluation of a systematic series of potent nucleoside-based inhibitors of MtBPL that contain modifications to the ribofuranosyl ring of the nucleoside. All compounds were characterized by isothermal titration calorimetry (ITC) and shown to bind potently with KD's below 2 nM. Additionally, we obtained high-resolution co-crystal structures for a majority of the compounds. Despite fairly uniform biochemical potency, the whole-cell Mtb activity varied greatly with minimum inhibitory concentrations (MIC) ranging from 0.78 to &gt;100 microM. Cellular accumulation studies in Mtb showed a nearly 10-fold enhanced accumulation of a C-2'-alpha analog over the corresponding C-2'-beta analog, consistent with their differential whole-cell activity.
