In Rhodospirillum rubrum, nitrogenase activity is regulated posttranslationally through the ADP-ribosylation of dinitrogenase reductase by dinitrogenase reductase ADP-ribosyltransferase (DRAT). Several DRAT variants that are altered both in the posttranslational regulation of DRAT activity and in the ability to recognize variants of dinitrogenase reductase have been found. This correlation suggests that these two properties are biochemically connected.
在深红红螺菌中,固氮酶活性通过固氮酶还原酶 ADP 核糖基转移酶(DRAT)对固氮酶还原酶进行 ADP 核糖基化作用在翻译后水平受到调控。已发现几种 DRAT 变体,它们在 DRAT 活性的翻译后调控以及识别固氮酶还原酶变体的能力方面均发生了改变。这种相关性表明这两种特性在生物化学上是相互关联的。
