Sequence variation in two ipaH genes of Shigella flexneri 5 and homology to the LRG-like family of proteins.

Molecular microbiology - 1 Oct 1991

Abstract excerpt

Oligonucleotide primers derived from the ipaH7.8 sequence have been used to determine the boundaries of DNA sequence homology among five ipaH genes on the invasion plasmid (pWR100) of Shigella flexneri 5, strain M9OT-W. The primary structure of IpaH4.5 has been established from DNA sequence analysis. The first 197 amino acids in IpaH7.8 were replaced in IpaH4.5 by a unique set of 251 amino acids, generating two...
