Site-directed mutagenesis of putative active site residues of MunI restriction endonuclease: replacement of catalytically essential carboxylate residues triggers DNA binding specificity.
Lagunavicius A, Siksnys V. Lagunavicius A, et al. Among authors: siksnys v. Biochemistry. 1997 Sep 16;36(37):11086-92. doi: 10.1021/bi963125i. Biochemistry. 1997. PMID: 9287151
Mapping of the conserved sequence regions in the restriction endonucleases MunI (C/AATTG) and EcoRI (G/AATTC) to the known X-ray structure of EcoRI allowed us to identify the sequence motif 82PDX14EXK as the putative catalytic/Mg2+ ion binding site of MunI [Siksnys, V …

DNA binding specificity of MunI restriction endonuclease is controlled by pH and calcium ions: involvement of active site carboxylate residues.
Lagunavicius A, Grazulis S, Balciunaite E, Vainius D, Siksnys V. Lagunavicius A, et al. Among authors: siksnys v. Biochemistry. 1997 Sep 16;36(37):11093-9. doi: 10.1021/bi963126a. Biochemistry. 1997. PMID: 9287152
Gel shift analysis reveals [Lagunavicius, A., & Siksnys, V. (1997) Biochemistry 36 (preceding paper in this issue)] that at pH 8.3 in the absence of Mg2+, MunI restriction endonuclease exhibits little DNA binding specificity, as compared with the D83A and E98A m …
