中文摘要：

乙醇酸氧化酶存在于细胞过氧化物酶体中，是光呼吸代谢的关键酶之一，能催化乙醇酸氧化生成乙醛酸，催化乙醛酸生成草酸；光呼吸与农业生产关系紧密．乙醇酸氧化酶是一种黄素蛋白，不同来源的乙醇酸氧化酶全酶分子质量和亚基相差很大．

英文摘要：

Glycolate Oxidase is in peroxisome of cell, and it is a key enzyme for plant photorespiration. It can catalyse glycolate to glyoxylate, and also catalyse glyoxylate to oxalate. Plant photorespiration does great relation with agriculture produce. Glycolate Oxidase is a flavoprotein. Molecular weight and subunit of glycolate Oxidase purificated from different materials differ greatly.
