Genome analysis with restriction endonucleases recognizing 4- or 5-base pair sequences of adenovirus type.
PURPOSE To detect the genetic changes in adenovirus type 4 (Ad4) by DNA restriction endonuclease analysis during 1993-1995, when no epidemic outbreak of conjunctivitis occurred. METHODS We evaluated 16 Ad4 strains from patients with acute viral conjunctivitis at four eye clinics in Sapporo, northern Japan. Seven strains were obtained during the period from December 1993 through March 1994 (fi...
متن کاملEvolutionary relationship between different subgroups of restriction endonucleases.
The type II restriction endonuclease SsoII shows sequence similarity with 10 other restriction endonucleases, among them the type IIE restriction endonuclease EcoRII, which requires binding to an effector site for efficient DNA cleavage, and the type IIF restriction endonuclease NgoMIV, which is active as a homotetramer and cleaves DNA with two recognition sites in a concerted reaction. We show...
متن کاملThe type IIB restriction endonucleases.
The endonucleases from the Type IIB restriction-modification systems differ from all other restriction enzymes. The Type IIB enzymes cleave both DNA strands at specified locations distant from their recognition sequences, like Type IIS nucleases, but they are unique in that they do so on both sides of the site, to liberate the site from the remainder of the DNA on a short duplex. The fact that ...
متن کاملTwo new restriction endonucleases from Proteus vulgaris.
Two novel sequence-specific endonucleases have been isolated from Proteus vulgaris, ATCC 13315. PvuI recognizes the sequence: 5' C G A T decrease C G 3' 3' G C increase T A G C 5' and PvuII recognizes the sequence: 5' C A G decrease C T G 3' 3' G T C increase G A C 5' and cleave as indicated by the arrow (decrease). PvuI is an isoschizomer of XorII, RshI, and XniI. No enzyme with the specificit...
متن کاملReactions of type II restriction endonucleases with 8-base pair recognition sites.
Type II restriction endonucleases usually recognize 4-6-base pair (bp) sites on DNA and cleave each site in a separate reaction. A few type II endonucleases have 8-bp recognition sites, but these seem unsuited for restriction, since their sites are rare on most DNA. Moreover, only one endonuclease that recognizes a target containing 8 bp has been examined to date, and this enzyme, SfiI, needs t...
