Active barnase variants with completely random hydrophonic cores
To test the minimum requirements for a core to provide sufficient structural integrity for enzymatic activity, Axe et al produced mutants of the ribonuclease barnase in which 12 of the 13 core residues have been randomly replaced by hydrophonic alternatives. A strikingly high proportion of these mut...

Zusammenfassung: | To test the minimum requirements for a core to provide sufficient structural integrity for enzymatic activity, Axe et al produced mutants of the ribonuclease barnase in which 12 of the 13 core residues have been randomly replaced by hydrophonic alternatives. A strikingly high proportion of these mutants (23%) retained enzymatic activity in vivo. |
