General annotation
Gene namegalE2
Rv numberRv0501
FunctionInvolved in galactose metabolism [catalytic activity: UDP-glucose = UDP-galactose].
ProductPossible UDP-glucose 4-epimerase GalE2 (galactowaldenase) (UDP-galactose 4-epimerase) (uridine diphosphate galactose 4-epimerase) (uridine diphospho-galactose 4-epimerase)
CommentsRv0501, (MTCY20G9.28), len: 376 aa. Possible galE2, UDP-glucose 4-epimerase, highly similar (except in N-terminus) to CAC31944.1|AL583925 possible glucose epimerase/dehydratase from Mycobacterium leprae (364 aa). N-terminus highly similar to S72923|B2168_C1_174|467075|AAA17259.1|U00018 hypothetical protein from Mycobacterium leprae (180 aa), FASTA scores: opt: 934, E(): 0, (89.6% identity in 164 aa overlap); and C-terminus highly similar to S72898|467050|AAA17234.1|U00018 hypothetical protein from Mycobacterium leprae (168 aa), FASTA scores: opt: 928, E(): 0, (82.7% identity in 168 aa overlap). Also highly similar to T36274|5123671|CAB45360.1|AL079345 probable epimerase from Streptomyces coelicolor (353 aa); and similar in part to other epimerases e.g. GALE_ECOLI|P09147 UDP-glucose 4-epimerase from Escherichia coli (338 aa), FASTA scores: opt: 241, E(): 6.7e-09, (28.2% identity in 294 aa overlap); etc. Belongs to the sugar epimerase family. Cofactor: NAD. Note that previously known as galE1.

ProteomicsIdentified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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). Translational start site supported by proteomics data (See Kelkar et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
