The function of Ensembl gene identifier ENSG00000165434 (PGM2L1, phosphoglucomutase 2 like 1) is as follows. Glucose 1,6-bisphosphate synthase using 1,3- bisphosphoglycerate as a phosphate donor and a series of 1-phosphate sugars, including glucose 1-phosphate, mannose 1-phosphate, ribose 1- phosphate and deoxyribose 1-phosphate, as acceptors (PubMed:17804405). In vitro, also exhibits very low phosphopentomutase and phosphoglucomutase activity which are most probably not physiologically relevant (PubMed:17804405). {ECO:0000269|PubMed:17804405, ECO:0000269|PubMed:18927083, ECO:0000269|PubMed:33979636}.
