General annotation
FunctionInvolved in lipopolysaccharide biosynthesis, in the conversion of UDP-galactopyranose into UDP-galactofuranose through a 2-keto intermediate [catalytic activity: UDP-D-galactopyranose = UDP-D-galacto-1,4-furanose].
ProductUDP-galactopyranose mutase Glf (UDP-GALP mutase) (NAD+-flavin adenine dinucleotide-requiring enzyme)
CommentsRv3809c, (MTV026.14), len: 399 aa. Glf (alternate gene name: ceoA), UDP-galactopyranose mutase (see citations below), identical to previously sequenced gene, and equivalent to Q9CDB8|GLF|ML0092 putative UDP-galactopyranose mutase from Mycobacterium leprae (413 aa), FASTA scores: opt: 2347, E(): 1.3e-140, (86.6% identity in 396 aa overlap). Also highly similar to others e.g. AAK61905|EPSJ UDP-galactopyranose mutase (protein involved in exopolysaccharides biosynthesis) from Streptococcus thermophilus (365 aa), FASTA scores: opt: 972, E(): 5.9e-54, (45.85% identity in 375 aa overlap); P37747|GLF_ECOLI|B2036 UDP-galactopyranose mutase from Escherichia coli strain K12 (367 aa), FASTA scores: opt: 958, E(): 4.5e-53, (43.55% identity in 379 aa overlap); O86897|CAP33FN from Streptococcus pneumoniae (369 aa) FASTA scores: opt: 954, E(): 8.1e-53, (44.8% identity in 375 aa overlap); etc. Cofactor: FAD (by similarity). N-terminal SHOWS similarity to FAD or NAD containing proteins.
Functional categoryCell wall and cell processes
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantEssential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
