Amino acid sequence of the K-peptide generated by limited proteolysis of glucose dehydrogenase from Bacillus megaterium by proteinase K1. 1984

K D Jany, and E Nitsche

Proteolysis of glucose dehydrogenase from Bacillus megaterium with proteinase K apparently generated two fragments. The small fragment, designated as K-peptide, was sequenced and its covalent structure was determined as Ser-Ser-Glu-Ala-Ser-Tyr-Val-Thr-Gly-Ile-Thr-Leu-Phe-Ala-Asp-Gly-Gly-Met-Thr- Gln-Tyr-Pro-Ser-Phe-Glu-Ala-Gly-Arg-Gly. The sequence analysis showed that the K-peptide consists of two identical fragments, one of which is lacking one serine residue at the amino-terminus.
