Gene disruption and gene replacement in Streptomyces via single stranded DNA transformation of integration vectors.

abstract：:The mammalian transcription factor SRF and the yeast regulatory protein MCM1 contain DNA binding domains that are 70% identical; moreover, both proteins can bind the serum response element in the human c-fos promoter. Here we present an analysis of MCM1 sequence specificity by selection of sites from random sequence o...
