Evidence for distinct kynureninase and hydroxykynureninase activities in Neurospora crassa.

abstract：:A method was devised to efficiently select isolates of Staphylococcus aureus 8325 in which Tn551, a transposon originating on the pI258 plasmid responsible for erythromycin resistance (Emr), had translocated to the host chromosome. This method consisted of selecting for Emr at 43 degrees C with a strain in which the p...
