FunctionPeptide chain release factor 2 directs the termination of translation in response to the peptide chain termination codons UGA and UAA.
ProductProbable peptide chain release factor 2 PrfB (RF-2)
CommentsRv3105c, (MTCY164.15c), len: 378 aa. Probable prfB, peptide chain release factor 2, equivalent to O32885|RF2_MYCLE|ML0667|MLCB1779.24c from Mycobacterium leprae, FASTA scores: opt: 2197, E(): 1.8e-126, (90.05% identity in 372 aa overlap); and also similar to other peptide chain release factors e.g. Q9L1S3|PRFB from Streptomyces coelicolor (368 aa), FASTA scores: opt: 1674, E(): 1.2e-94, (69.3% identity in 365 aa overlap); O67695|RF2_AQUAE|PRFB|AQ_1840 from Aquifex aeolicus (373 aa), FASTA scores: opt: 1082, E(): 1.3e-58, (44.45% identity in 369 aa overlap); P28367|RF2_BACSU from B. subtilis (366 aa), FASTA scores: opt: 1030, E(): 1.9e-55, (44.0% identity in 359 aa overlap); etc. Also related to Q10605|MTCY373.19|RF1_MYCTU|Rv1299|MT1338 peptide chain release factor 1 (rf-1) (357 aa), FASTA scores: opt: 646, E(): 1.1e-34, (38.6% identity in 350 aa overlap). Contains prokaryotic-type class I peptide chain release factors signature (PS00745). Belongs to the prokaryotic and mitochondrial release factors family.
Functional categoryInformation pathways
ProteomicsIdentified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow 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 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 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 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).
