Descrizione libro Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The heat-shock proteins in E. coli are transiently overexpressed af ter shift to a higher growth temperature. The genes that encode the HSPs are preceded by promoters transcribed in vitro by a form of RNA poly 32 32 merase holoenzyme containing a 32-kd a subunit (Ea ). The a subunit is encoded by the rpoH (htpR) gene, previously identified as a positive 32 effector of the heat-shock response. Our evidence suggests that Ea is the enzyme that transcribes heat-shock genes at all temperatures. The level 32 of a may be regulated at several points: Accumulation of rpoH mRNA 32 is affected by temperature shift, a synthesis is regulated posttranscrip 32 tionally, and a is an unstable molecule with a tl/2 of 5 min. Many mu tations in the HSPs are shown to have defects in proteolysis. References Baker. T. A. , Grossman. A. D . . and Gross. C.
