Abstract

A model for the structure of dimethylamine dehydrogenase was generated using the crystal coordinates of trimethylamine dehydrogenase. Substrate is bound in trimethylamine dehydrogenase by cation-pi bonding, but modeling of dimethylamine dehydrogenase suggests that secondary amines are bound by a mixture of cation-pi and conventional hydrogen bonding. In dimethylamine dehydrogenase, binding is orientationally more specific and distinct from those proteins that bind tertiary and quaternary amine groups.

摘要

利用三甲胺脱氢酶的晶体坐标生成了二甲胺脱氢酶的结构模型。底物在三甲胺脱氢酶中通过阳离子-π键结合,但二甲胺脱氢酶的模型表明仲胺是通过阳离子-π键和传统氢键的混合方式结合的。在二甲胺脱氢酶中,结合在方向上更具特异性,且与那些结合叔胺和季胺基团的蛋白质不同。
