Ribonuclease B (RNase B)
Introduction
Ribonuclease B is structurally the same as RNase A. However is has an additional catalytic activity caused by the attachment of polysaccharrides at the Asn-34. This small change allows RNase B to hydrolyze double-stranded RNA at ionic strengths where RNase A has no activity. This shows that small changes in the active sites of very similar molecules can lead to todally new roles and activities.
