Structural basis for RNA-genome recognition during bacteriophage Qβ replication.

abstract：:Cultured mammalian cells transduced with the Escherichia coli gene, Ecogpt, synthesize the bacterial enzyme xanthine-guanine phosphoribosyl transferase (XGPT) (1). This paper describes a method for measuring XGPT activity in crude cell extracts by following the conversion of 14C-xanthine (X) to 14C-xanthine monophosph...
