Heat-shock-induced proteins from Myxococcus xanthus.
Optimal conditions for two-dimensional gel electrophoresis of total cellular proteins from Myxococcus xanthus were established. Using these conditions, we analyzed protein patterns of heat-shocked M. xanthus cells. Eighteen major spots and 15 minor spots were found to be induced by heat shock. From N-terminal sequences of 15 major spots, DnaK, GroEL, GroES, alkyl hydroperoxide reductase, aldehy...
متن کاملCharacterization of a small heat shock protein, Mx Hsp16.6, of Myxococcus xanthus.
A number of heat shock proteins in Myxococcus xanthus were previously identified by two-dimensional (2D) gel electrophoresis. One of these protein was termed Mx Hsp16.6, and the gene encoding Mx Hsp16.6 was isolated. Mx Hsp16.6 consists of 147 amino acid residues and has an estimated molecular weight of 16,642, in accordance with the apparent molecular mass in the 2D gel. An alpha-crystallin do...
متن کاملHDAC Inhibitors and Heat Shock Proteins (Hsps)
Epigenetic alterations, including DNA acetylation, hypermethylation and hypomethylation, and the associated transcriptional changes of the affected genes are central to the evolution and progression of various human cancers, including pancreatic cancer. Cancer-associated epigenetic alterations are attractive therapeutic targets because such epigenetic alterations, unlike genetic changes, are po...
متن کاملIdentification of enhancer binding proteins important for Myxococcus xanthus development.
Enhancer binding proteins (EBPs) control the temporal expression of fruiting body development-associated genes in Myxococcus xanthus. Eleven previously uncharacterized EBP genes were inactivated. Six EBP gene mutations produced minor but reproducible defects in fruiting body development. One EBP gene mutation that affected A-motility produced strong developmental defects.
متن کاملIntegral proteins of the extracellular matrix fibrils of Myxococcus xanthus.
The extracellular matrix fibrils of Myxococcus xanthus are mediators of cell-cell cohesion and as such are required for the maintenance of the social lifestyle characteristic of these prokaryotes. The fibrils have also been implicated as factors involved in contact-mediated cell interactions and in signal exchange. The fibrils are extracellular carbohydrate structures with associated proteins. ...
