Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Endonuclease III (Nth) enzyme from Escherichia coli is involved in base excision repair of oxidised pyrimidine residues in DNA. The Schizosaccharomyces pombe Nth1 protein is a sequence and functional homologue of E. coli Nth, possessing both DNA glycosylase and apurinic/apyrimidinic (AP) lyase activity. Here, we report the construction and characterization of the S. pombe nth1 mutant. The nth1 mutant exhibited ... [more]
