Previous studies (28–30) have shown that an AG → GG mutation at the 3′ splice site of mammalian pre-mRNAs does not have a significant effect on the efficiency of the first step of splicing if the substrate contains a functional branchpoint sequence, followed by a pyrimidine tract. Howeve...

Steady state kinetic evidence for an acyl-enzyme intermediate in reactions catalyzed by bovine spleen cathepsin B. Cathepsin B from bovine spleen was shown to catalyze transacylation reactions between esters of N-substituted amino acids and nucleophiles. These reactions... AS Bajkowski,A Frankfater -...
