Sequence analysis of a cloned cDNA coding for bovine seminal ribonuclease

The sequence of a cloned cDNA coding for bovine seminal ribonuclease, an enzyme secreted in the bull seminal vesicles, was determined. The cDNA starts at the amino acid residue 47 and terminates 12 nucleotides beyond the consensus sequence AAUAAA in the 3' non-coding region of the mRNA. Northern blotting analysis shows that the mRNA for bovine seminal ribonuclease consists of about 950 nucleotides, a value that is similar to that of other mRNAs coding for ribonucleases of the pancreatic type.
