Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.[https://www.uniprot.org/uniprot/PPTT_MYCTU PPTT_MYCTU] Transfers the 4'-phosphopantetheine moiety from coenzyme A to a Ser of acyl-carrier-protein (PubMed:9831524, PubMed:16709676, PubMed:25785780, PubMed:28203522). Involved in post-translational modification of various type-I polyketide synthases required for the formation of both mycolic acids and lipid virulence factors (PubMed:16709676). Acts on Pks13, Mas, PpsA, PpsB, PpsC and PpsD (PubMed:16709676, PubMed:28203522). Also acts on AcpM, the meromycolate extension acyl carrier protein (PubMed:25785780). In addition, is involved in the activation of the acyl carrier protein MbtL and the nonribosomal peptides synthases MbtB and MbtE, which are involved in the biosynthesis of the siderophore mycobactin (PubMed:9831524, PubMed:28203522).<ref>PMID:16709676</ref> <ref>PMID:25785780</ref> <ref>PMID:28203522</ref> <ref>PMID:9831524</ref> Required for the replication and survival of Mycobacterium during the acute and chronic phases of infection in mice.<ref>PMID:23308068</ref> | ||
