Physical and Genetic Map of the Neisseria Gonorrhoeae Strain MS11-N198 Chromosome

Mol Microbiol. 1991 Oct;5(10):2529-39. doi: 10.1111/j.1365-2958.1991.tb02099.x.


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.
