Gene Rv1564c (glgX)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Possibly 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 | Probable maltooligosyltrehalose synthase TreX |
| Comments | Rv1564c, (MTCY48.01), len: 721 aa. Probable treX (previously called glgX), Maltooligosyltrehalose synthase. Strong similarity to D83245|g1890053 treX, glycogen debranching enzyme (glgX) from Sulfolobus acidocaldarius (713 aa), FASTA score: opt: 2396, E(): 0, (48.4% identity in 709 aa overlap); similar to GLGX_HAEIN|P45178 glycogen operon protein glgx (659 aa), FASTA scores: opt: 1512, E(): 0, (42.3% identity in 645 aa overlap). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | 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 | 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
