Belongs to class-III of pyridoxal-phosphate-dependent aminotransferases. Cofactor: pyridoxal phosphate. |
| Functional category | Intermediary metabolism and respiration |
| 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 culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
