GHKL, an emergent ATPase/kinase superfamily.
Major cold shock protein of Escherichia coli.
When exponentially growing Escherichia coli cell cultures were transferred from 37 degrees C to 10 degrees C or 15 degrees C, the production of a 7.4-kDa cytoplasmic protein (CS7.4) was prominently induced and revealed that the gene encodes a hydrophilic protein of 70 amino acid residues.
Cold shock induces a major ribosomal-associated protein that unwinds double-stranded RNA in Escherichia coli.

The requirement for CsdA in derepression of heat-shock protein synthesis is a cold shock-induced function possibly mediated by destabilization of secondary structures previously identified in the rpoH mRNA.
CspA, the Major Cold-shock Protein of Escherichia coli, Is an RNA Chaperone*
It is proposed that CspA functions as an RNA chaperone to prevent the formation of secondary structures in RNA molecules at low temperature and may be crucial for efficient translation of mRNAs at low temperatures and may also have an effect on transcription.
MazF cleaves cellular mRNAs specifically at ACA to block protein synthesis in Escherichia coli.
Toxin-antitoxin systems in bacteria and archaea.
Almost all bacteria and many archaea contain genes whose expression inhibits cell growth and may lead to cell death when overproduced, reminiscent of apoptotic genes in higher systems. The cellular…
Phylogenetic distribution of branched RNA-linked multicopy single-stranded DNA among natural isolates of Escherichia coli
The hypothesis that msDNA-synthesizing systems, including reverse transcriptase genes, were acquired recently and independently in different lineages of E. coli is supported.
The CspA family in Escherichia coli : multiple gene duplication for stress adaptation
The E. coli CspA family is described, consisting of nine genes from cspA to cspI, which resulted from a number of gene duplications and, after subsequent adaptation, resulted in specific groups of genes that respond to different environmental stresses.
Regulation of growth and death in Escherichia coli by toxin–antitoxin systems
Escherichia coli K-12 contains at least 36 toxin genes, the expression of which causes growth inhibition and eventual death. These toxins are usually co-expressed with their cognate antitoxins in…
Histidine kinases: diversity of domain organization
The previously known so‐called transmitter domain of histidine kinase is further dissected into two domains: a CA (Catalytic ATP‐binding) domain and a DHp (Dimerization Histidine phosphotransfer) domain for class I, or a CA domain and an HPt (Histidine‐containing PhosphotransFER) domain with significant differences between them.
