摘  要:
植物β-半乳糖苷酶是一类糖苷水解酶,能够从β-D-半乳聚糖或寡聚糖支链非还原末端切除β-D-半乳糖残基。β-半乳糖苷酶广泛分布于各种植物中,通过对细胞壁的重塑参与植物生长发育过程。总结了植物β-半乳糖苷酶生化与分子生物学方面的最新研究进展,并就其结构域及催化机制、生化特性、亚细胞定位和表达模式、生理功能等方面展开详述。

摘  要:
Plant β-galactosidase is a kind of glycoside hydrolase, which can remove terminal β-D-galactose residues from the non-reducing end of β-D-galactan or the branched side chain of oligosaccharide. It is widely distributed in various plants and participates in plant growth and development through remodeling cell walls. In this paper, the latest advances in biochemical and molecular biology of plant β-galactosidase were summarized. The structure domain, catalytic mechanism, biochemical characteristics, subcellular localization and expression patterns, physiological functions and so on were described in detail.
