I am using the enzyme keratanase II to digest a proteoglycan prior to
amino-acid sequence analysis. As the molecular weight of the enzyme is
very similar to that of the digestion product I am worried that I will end
up with peptide sequence from keratanase II rather than that of my
proteoglycan. So far I have found no homologous peptides in a Genbank
Does any one have any amino-acid or DNA sequence for keratanase II?
