Species-specific uptake of DNA by gonococci is mediated by a 10-base-pair sequence.

Abstract

Piliated Neisseria gonorrhoeae are known to be transformed less readily if transforming DNA competes with DNA containing the 10-bp sequence GCCGTCTGAA. It has been postulated that the 10-bp sequence is a recognition sequence which is required for efficient DNA uptake. We show that the presence of various forms of this 10-bp sequence results in increased uptake of double-stranded DNA into a DNase-resistant state and allows genetic transformation by an otherwise nontransformable plasmid.
