Comparative analysis of proteins induced by heat shock salinity and osmotic stress in the nitrogen-fixing cyanobacterium Anabaena sp. strain L-31.

摘要

Heat, salinity, or osmotic stress influenced protein synthesis in nitrogen-fixing Anabaena sp. strain L-31. Salinity and osmotic stresses were identical and specifically induced 15 polypeptides. Four polypeptides were unique to heat shock, and four other polypeptides were induced under every stress. The results demonstrate a commonality and a stress specificity of protein synthesis regulation.
