Abstract

A tentative primary structure of the NADP-specific glutamate dehydrogenase [L-glutamate: NADP oxidoreductase (deaminating), EC 1.4.1.4] from Neurospora crassa has been determined. The proposed sequence contains 452 amino-acid residues in each of the identical subunits of the hexameric enzyme. Comparison of the sequence with that of the bovine liver enzyme reveals considerable homology in the amino-terminal portion of the chain, including the vicinity of the reactive lysine, with only shorter stretches of homology within the carboxyl-terminal regions. The significance of this distribution of homologous regions is discussed.

摘要

粗糙脉孢菌中NADP特异性谷氨酸脱氢酶[L-谷氨酸:NADP氧化还原酶(脱氨基),EC 1.4.1.4]的初步一级结构已被确定。所提出的序列在六聚体酶的每个相同亚基中包含452个氨基酸残基。将该序列与牛肝酶的序列进行比较,发现在链的氨基末端部分有相当大的同源性,包括反应性赖氨酸附近,而在羧基末端区域内只有较短的同源片段。讨论了同源区域这种分布的意义。
