General annotation
| Type | CDS |
| Function | Unknown. GCPE is an essential gene. |
| Product | Probable GcpE protein |
| Comments | Rv2868c, (MTV003.14c), len: 387 aa. Probable gcpE protein (protein e), equivalent to Q9CBU5|GCPE|ML1581 hypothetical protein GCPE from Mycobacterium leprae (392 aa), FASTA scores: opt: 2247, E(): 6.8e-134, (87.65% identity in 388 aa overlap). Highly similar to essential gene of unknown function from Escherichia coli and other prokaryotes e.g. Q9X7W2|GCPE_STRCO|SC6A5.16 GCPE protein homolog from Streptomyces coelicolor (384 aa), FASTA scores: opt: 1965, E(): 3.8e-116, (78.2% identity in 385 aa overlap); P54482|GCPE_BACSU GCPE protein homolog from Bacillus subtilis (377 aa), FASTA scores: opt: 1157, E(): 2.6e-65, (49.55% identity in 351 aa overlap); P27433|GCPE_ECOLI|B2515|Z3778|ECS3377 GCPE protein (protein E) from Escherichia coli strains K12 and O157:H7 (372 aa), FASTA scores: opt: 984, E(): 2e-54, (44.15% identity in 360 aa overlap); etc. Belongs to the GCPE family. |
| Functional category | Conserved hypotheticals |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh 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). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
