磷酸甘露糖变位酶2（英語：Phosphomannomutase 2）是一种由基因 PMM2 编码的酶[1][2]。
PMM2是一种变位酶，将甘露糖-6-磷酸催化异构为甘露糖-1-磷酸。甘露糖-1-磷酸是鸟苷二磷酸甘露糖的前体，necessary for the synthesis of dolichol-P-oligosaccharides. Mutations in the gene have been shown to cause defects in the protein glycosylation pathway manifest as carbohydrate-deficient glycoprotein syndrome type I.[2]
