Penicillin-insensitive transglycosylase; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits) (By similarity). Has little peptidoglycan hydrolytic activity; however it inhibits the synergistic peptidoglycan hydrolysis of RipA plus RpfB.

Mannosyltransferase PimE; Catalyzes the alpha-1,2 addition of a mannose residue from polyprenol-phosphate-mannose (PPM) to a monoacyl phosphatidylinositol pentamannoside (AcPIM5) to generate a monoacyl phosphatidylinositol hexamannoside (AcPIM6).

Rv0541c, (MTCY25D10.20c), len: 449 aa. Probable conserved integral membrane protein, highly similar (except first 40 residues) to CAB76994.1|AL159178 putative integral membrane protein from Streptomyces coelicolor (456 aa). Also some similarity to Q13724|GCS1_HUMAN mannosyl-oligosaccharide glucosidase (834 aa), FASTA scores: opt: 150, E(): 0.013, (27.1% identity in 339 aa overlap). Contains PS00041 Bacterial regulatory proteins,araC family signature.

Possible arabinofuranosyltransferase AftD; Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall. Catalyzes the addition of an arabinofuranosyl (Araf) residue from the sugar donor decaprenyl-phospho-arabinose (DPA) on the C-3 of an alpha-(1->5)-linked Araf from the arabinan backbone of AG.

Rv0955, (MTCY10D7.19c), len: 455 aa. Probable conserved integral membrane protein, highly similar to AL035500|MLCL373_6 putative membrane protein from Mycobacterium leprae (430 aa), FASTA score: (75.9% identity in 419 aa overlap); and AAL05878.1|AF411607_2|AF411607 unknown protein from Mycobacterium avium subsp. paratuberculosis (409 aa). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al.,2004).

Rv3604c, (MTCY07H7B.18), len: 397 aa. Probable conserved ala-, arg-, pro-rich transmembrane protein,equivalent to O69526|MLCB2548.03c|ML0228 putative membrane protein from Mycobacterium leprae (432 aa), FASTA scores: opt: 869, E(): 2.9e-31, (59.7% identity in 432 aa overlap). Contains two possible membrane-spanning domains. N-terminus shortened since first submission (previously 462 aa). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

30S ribosomal protein S6 RpsF; Binds together with S18 to 16S ribosomal RNA.

Possible arabinofuranosyltransferase AftB; Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall. Catalyzes the transfer of arabinofuranosyl (Araf) residues from the sugar donor decaprenyl-phospho-arabinose (DPA) to the arabinan domain to form terminal beta-(1->2)-linked Araf residues, which marks the end point for AG arabinan biosynthesis before decoration with mycolic acids.

Putative primosomal protein N' PriA (replication factor Y); Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily.
