Functional categoryregulatory proteins

Mutationessential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). M. tuberculosis H37Rv kpdDE mutant shows increased virulence in SCID mice (See Parish et al., 2004).
