FunctionComponent of the translational apparatus. Furnishes a means for formation of correctly charged GLN-tRNA(GLN) through the transamidation of misacylated GLU- tRNA(GLN) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-GLU-tRNA(GLN) [catalytic activity: ATP + L-glutamyl-tRNA(GLN) + L-glutamine = ADP + phosphate + L-glutaminyl-tRNA(GLN) + L-glutamate].
ProductProbable glutamyl-tRNA(GLN) amidotransferase (subunit B) GatB (Glu-ADT subunit B)
CommentsRv3009c, (MT3089, MTV012.23c), len: 509 aa. Probable gatB, Glu- tRNA-Gln amidotransferase, subunit B , equivalent to O33107|GATB_MYCLE|MLCB637_15 glutamyl-tRNA(GLN) amidotransferase from Mycobacterium leprae (509 aa), FASTA scores: opt: 2973, E(): 2.9e-173, (88.4% identity in 509 aa overlap). Also highly similar to other Glu- tRNA-Gln amidotransferases e.g. Q9Z578|GATB|SC8D9.13 from Streptomyces coelicolor (504 aa), FASTA scores: opt: 2264, E(): 3.6e-130, (66.0% identity in 495 aa overlap); P74215|GATB_SYNY3|SLL1435 from Synechocystis sp. strain PCC 6803 (519 aa), FASTA scores: opt: 1289, E(): 6.7e-71, (42.0% identity in 485 aa overlap); Q9X100|GATB_THEMA|TM1273 glutamyl-tRNA(GLN) amidotransferase from Thermotoga maritima (482 aa), FASTA scores: opt: 1165, E(): 2.2e-63, (40.05% identity in 487 aa overlap); etc. For more information about function, see citation below. Similar to many members of the pet112 family. Belongs to the GatB family.
Functional categoryInformation pathways
ProteomicsIdentified 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 30 days but not 90 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).
