Heterogeneity of the amino-acid sequences of Escherichia coli Shiga-like toxin type-I operons.

A W Paton1, L Beutin, J C Paton.   

Abstract

PCR was used to amplify approx. 1470-bp segments of DNA containing complete Shiga-like toxin type I (sltI) operons from Escherichia coli strains belonging to serotypes O48:H21, O111:H- and OX3:H8. These fragments were cloned and DNA sequence analysis identified several variations, as compared with published sltI sequences. All three sltI genes analysed were more closely related to Shiga toxin-encoding genes (sht) of Shigella dysenteriae type 1, than to previously published E. coli phage-encoded sltI genes. The greatest deviation in deduced amino acid (aa) sequence was observed in the SltI protein from the OX3:H8 strain, which differed from the phage 933J-encoded SltI by 9 aa in the A subunit and 3 aa in the B subunit.
