Ammonia assimilation in rumen bacteria: a review
1Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, The Chinese Academy of Sciences, Hunan, PR China.
Abstract:
In the rumen bacteria, ammonia as the end product of nitrogen is incorporated into carbon skeleton (α-ketoglutarate) to yield glutamine and glutamate which are important nitrogen donors in nitrogenous compounds metabolism in cells. The enzymes glutamine synthetase, glutamate synthetase, and glutamate dehydrogenase are involved in these processes. Some experimental results have proven that the global nitrogen regulation system may participate in the regulation of assimilation of ammonia in rumen bacteria. This review offers a current perspective on the pathways and key enzymes of ammonia assimilation in rumen bacteria with the possible molecular regulation strategy, while points out the further research direction.
