The swi4+ gene of Schizosaccharomyces pombe encodes a homologue of mismatch repair enzymes.

abstract：:Extracts of the human glioma cell line A1235 (lacking O(6)-methylguanine-DNA methyltransferase) are known to restore a G:T mismatch to a normal G:C pair in a G:T-containing model (45 bp) DNA substrate. Herein we demonstrate that substitution of G:T with O(6)-methylguanine:T (m6G:T) results in extract-induced intra-str...
