Status

Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Involved in the biosynthesis of the maltose-1-phosphate (M1P) building block required for alpha-glucan production by the key enzyme GlgE (PubMed:18808383, PubMed:27513637). Catalyzes the formation of an alpha-1,4 linkage between glucose from ADP-glucose and glucose 1-phosphate (G1P) to yield maltose-1-phosphate (M1P) (PubMed:27513637). Also able to catalyze the elongation of the non-reducing ends of glycogen, maltodextrin and maltoheptaose using ADP-glucose as sugar donor, however the rate of the reaction appears to be too low to be physiologically relevant (PubMed:27513637). GlgM is also able to use UDP-glucose as sugar donor with G1P, however, it is less efficient than with ADP-glucose (PubMed:27513637). UDP-glucose is not used as sugar donor when glycogen is used as acceptor (PubMed:27513637).2 Publications

Miscellaneous

Maltose-1-phosphate (M1P) is generated by two alternative routes: the TreS-Pep2 branch and the GlgC-GlgM branch, however it seems that TreS-Pep2 branch provides most of M1P for the GlgE pathway in M.tuberculosis.1 Publication
Attempts to disrupt both the Rv3032 gene and glgA in order to create a mutant simultaneously deficient in both alpha-1,4-glucosyltransferases turned out to be unsuccessful. Thus, M.tuberculosis H37Rv requires a functional copy of at least one of these two genes for growth.1 Publication

Inactivation of glgM affects the production of extracellular alpha-glucan (two-fold reduction), but not that of intracellular glycogen and 6-O-methylglucosyl lipopolysaccharides (MGLP) (PubMed:18808383, PubMed:27513637). Cells lacking this gene are also impaired in their ability to persist in both the spleen and the lungs of mice (PubMed:18808383). Combined inactivation of both glgM and ostA is lethal, potentially due to accumulation of toxic levels of ADP-glucose (PubMed:27513637). Combined inactivation of both glgM and treS results in absence of alpha-glucan (PubMed:27513637).2 Publications
