Gene Rv1326c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in glycogen biosynthesis (cytoplasmic polysaccharides) (third step) [catalytic activity: formation of 1,6-glucosidic linkages of glycogen]. |
| Product | 1,4-alpha-glucan branching enzyme GlgB (glycogen branching enzyme) |
| Comments | Rv1326c, (MTCY130.11c), len: 731 aa. glgB, 1,4-alpha-glucan branching enzyme, similar to others e.g. GLGB_ECOLI|P07762 Escherichia coli (728 aa), FASTA scores: opt: 2330, E(): 0, (48.7% identity in 719 aa overlap). Similar to other Mycobacterium tuberculosis putative alpha-glucan branching enzymes Rv1562c, Rv1563c. Belongs to family 13 of glycosyl hydrolases, also known as the alpha-amylase family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in the culture filtrate and whole cell lysates of M. tuberculosis H37Rv but not the membrane protein fraction (See de Souza 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 by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene, determined by allelic exchange experiments (See Sambou et al., 2008). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
