Escherichia coli ribosomal RNA transcription: regulatory roles for ppGpp, NTPs, architectural proteins and a polymerase-binding protein.

Jay D Gralla1.   

Abstract

Ribosomal RNA transcription can limit the rate of Escherichia coli growth and is subject to complex regulation. Somehow, the cell is able to sense the general nutritional environment and adjust rRNA transcription so that an appropriate number of ribosomes is produced. This review discusses the current state of affairs, including recent information about the involvement of two nucleotide regulators, two architectural protein regulators, one new co-regulator and stalled ribosomes.
