Mycobacterium tuberculosis PanR0603

Protein-related phenotypes

Virulence Factors
PcaA
Cyclopropane synthase that incorporates a single proximal cycloproprane ring on the <alpha>-mycolic acids and the production of cord factor in the cell wall; Required for virulence and persistance
Inhibition of cyclopropanation of cell wall mycolic acid can result in a change in lipid fluidity and cell wall permeability, and therefore a change in resistance to reactive oxygen intermediates (ROIs) and reactive nitrogen intermediates (RNIs)
MmaA4
Methyltransferase forms methoxy and keto derivatives of the meromycolic acid chain
Hypothetical protein
Glutamate racemase
PDIM (phthiocerol dimycocerosate)
Play a mainly structural role in providing a stable base for the insertion of other lipid and also play a role as a fluidity modifier, whose function could be to modulate cell wall viscosity
Antigen 85
Mycolyltransferase activity that transfer long-chain mycolic acids to trehalose derivatives (i.e., cord factor, a toxic glycolipid consisting of two mycolic acid molecules linked to trehalose by the hydroxyl groups of carbons 6 and 6' --> trehalose 6,6'-dimycolate (TDM), is an important immunomodulatory component of the cell wall), pivotal for the biosynthesis of the mycobacterial cell wall and for the survival of mycobacteria; Binds the cell matrix protein fibronectin thereby enhancing the uptake of mycobacteria macrophages via complement-mediated phagocytosis
Possible conserved protein cpsA
Mycobactin
Cell-association mycobactin participates in iron internalization and/or to serve as a temporary iron-holding molecule to prevent sudden influx of excess iron if the metal suddenly becomes available after a period of iron limitation
Endonuclease IV
end
PhoP
Senses Mg2+ starvation, controls expression of genes involved in surface remodeling and adaptation to intracellular growth
Probable transcriptional regulatory protein
Probable DNA repair protein RecN (recombination protein n)
Probable transcriptional regulatory protein (probably crp/fnr-family)
crp
SodC
Copper/zinc-dependent enzyme, responsible for a small part of total SOD activity in M. tuberculosis
KatG
Catalase:peroxidase degrades H2O2 and organic peroxides, the major role is to catabolize the peroxides generated by phagocyte NADPH oxidase
SodA
Iron-dependent enzyme, important fro survival of intracellular pathogens during infection
GPL locus
Mce1
Probable conserved mce associated transmembrane protein
Heme uptake
Protein kinase G
Mce2
Copper exporter
F0F1 ATP synthase subunit A
Probable polyketide synthase pks5
Hypothetical protein
Lysyl-tRNA synthetase
Fused nitrate reductase
Fibronectin-binding protein
Exochelin (smegmatis)
Pyruvate dehydrogenase subunit E1
Trehalose-recycling ABC transporter
Possible transmembrane phospholipid biosynthesis bifunctionnal enzyme plsc: putative l-3-phosphoserine phosphatase (o-phosphoserine phosphohydrolase) (psp) (pspase) + 1-acyl-sn-glycerol-3-phosphate acyltransferase (1-agp acyltransferase) (1-agpat) (lysoph
Mce3
Carboxylesterase
Prolyl-tRNA synthetase

ESX-2 (T7SS)
MymA operon
Molybdopterin biosynthesis-like protein MoeZ
Possible cyclase
Probable transposase
