P. Stadtler et al., PURIFICATION AND CHARACTERIZATION OF THE RESTRICTION-ENDONUCLEASE ITAI FROM ILYOBACTER-TARTARICUS RECOGNIZING 5'-GC-DOWN-ARROW-NGC-3', Gene, 137(2), 1993, pp. 347-348
ItaI, an isoschizomer of the subclass IIW [Kessler and Manta, Gene 92
(1990) 1-248] restriction endonuclease (ENase), Fnu4HI [Leung et al.,
Nucleic Acids Res. 6 (1979) 17-25], has been isolated from Ilyobactel
tartaricus. The ENase has the five-base palindromic recognition sequen
ce, 5'-GC down arrow NGC-3'. It cleaves behind the second nucleotide a
nd produces a one-nt 5' overhang.
