Two conserved histidine residues (His-101 and His-271) appear to be essential components in the active site of the enzyme xylose (glucose) isomerase (EC 5.3.1.5). These amino acid residues were targeted for mutagenesis on the basis of sequence homology among xylose isomerases isolated from Escherichia coli, Bacillus subtilis, Ampullariella sp. strain 3876, and Streptomyces violaceus-niger. Each...
UNLABELLED We systematically analyzed the capability of the major cytosolic chaperones of Escherichia coli to cope with protein misfolding and aggregation during heat stress in vivo and in cell extracts. Under physiological heat stress conditions, only the DnaK system efficiently prevented the aggregation of thermolabile proteins, a surprisingly high number of 150-200 species, corresponding to ...
