Abstract

SUMMARY: The unicellular cyanobacterium contains both photoreactivation and excision repair mechanisms for correcting UV-induced damage to its cellular DNA. An 11.5 kb RI fragment was isolated from a cosmid bank of and was shown to complement a deletion in S. 17 and JC10289. These strains showed increased survival to UV and methyl methanesulphonate (MMS) when transformed with the cyanobacterial DNA fragment, and also showed filamentation in response to UV irradiation. Preliminary analysis of the protein encoded by the cyanobacterial DNA fragment indicated a major protein of 39000 Da; this is very similar in size to the protein of
