Gene Rv1563c (glgY)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in trehalose biosynthesis (protective effect). Mycobacteria can produce trehalose from glucose 6-phosphate and UDP-glucose (the OtsA-OtsB pathway) from glycogen-like alpha(1-->4)-linked glucose polymers (the TreY-TreZ pathway) and from maltose (the TreS pathway). |
| Product | Maltooligosyltrehalose synthase TreY |
| Comments | Rv1563c, (MTCY48.02), len: 765 aa. TreY (previously called glgY), maltooligosyl trehalose synthase, confirmed biochemically (see citation below). Strong similarity to Q44315|63343 trey maltooligosyl trehalose synthase from arthrobacter SP (775 aa), fasta scores: opt: 1953, E(): 0; (46.0% identity in 789 aa overlap). Some similarity to alpha-amylases and to MTCY48.03 (30.2% identity in 215 aa overlap). May catalyse conversion of maltodextrins to maltooligosyl trehaloses. Also similar to Mycobacterium tuberculosis glgB (Rv1326c), treZ (Rv1562c). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | 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). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Check for mutants available at TARGET website |
