摘　要：

葡萄糖磷酸变位酶(PGM)是生物新陈代谢的关键酶, 可催化葡萄糖-1-磷酸和葡萄糖-6-磷酸相互转化。在植物中, PGM分为胞质型PGM和质体型PGM。胞质型PGM参与蔗糖的代谢; 质体型PGM参与淀粉的合成。近期发现, PGM在植物生长发育中起到重要作用。本文主要对植物中葡萄糖磷酸变位酶的分类、分子性质及功能等方面进行综述。

Abstract:

Phosphoglucomutase (PGM), which interconverts between glucose-1-phosphate and glucose-6-phosphate, is a key enzyme of metabolism. PGM is classed into the cPGM (cytosol-localized PGM) and pPGM (plastid-localized PGM). cPGM participates in sucrose metabolism, and pPGM participates in starch synthetic. PGM plays an important role in the plant growth and development. This paper reviews the classification, molecular characterization and function of phosphoglucomutase in plants.

Key words: phosphoglucomutase; sucrose metabolism; starch synthetic; plant development
