Physical and genetic map of the <i>Neisseria gonorrhoeae</i> strain MS11‐N198 chromosome

Abstract

A macro-restriction map of the Neisseria gonorrhoeae chromosome was constructed using the enzymes Nhel and Spel. Combinations of one- and two-dimensional electrophoresis of completely or partially digested chromosomal DNA were performed to align the restriction fragments. The chromosome is circular, with an estimated size of 2.33 Mb +/- 35 kb. A genetic map was derived from the physical map; positions of over 60 defined loci were determined by Southern hybridization.
