虽然水稻（Oryza sativa L.）甜菜碱醛脱氢酶（BADH; EC 1.2.1.8）基因同源物OsBADH 1和OsBADH 2。我们发现OsBADH 1能有效地催化乙醛的氧化，而OsBADH 2的活性很低。OsBADH 1 mRNA的积累在淹水处理后减少，但在复氧后迅速恢复。我们证实OsBADH 1定位于过氧化物酶体。本文探讨了OsBADH 1在水稻过氧化物酶体过氧化氢酶氧化乙醛过程中可能的生理功能。(C)2009年欧洲生物化学学会联合会。由Elsevier B出版。V.保留所有权利。
Although rice (Oryza sativa L.) produces little glycine betaine (GB), it has two betaine aldehyde dehydrogenase (BADH; EC 1.2.1.8) gene homologs (OsBADH1 and OsBADH2). We found that OsBADH1 catalyzes the oxidation of acetaldehyde efficiently, while the activity of OsBADH2 is extremely low. The accumulation of OsBADH1 mRNA decreases following submergence treatment, but quickly recovers after re-aeration. We confirmed that OsBADH1 localizes in peroxisomes. In this paper, a possible physiological function of OsBADH1 in the oxidation of acetaldehyde produced by catalase in rice plant peroxisomes is discussed.
