摘要:
Provided are methods of producing a novel collagen peptide composition, and a DPP-4 inhibitor and antihyperglycemics that comprise the above-mentioned collagen peptide composition. Ginger rhizome-derived enzymes are added to and break down a collagen and/or gelatin solution to generate peptide compositions comprising peptides represented by X-Hyp-Gly (wherein X represents an amino acid residue other than Gly, Hyp, and Pro). The thus obtained collagen peptide composition has a high DPP-4 inhibitory activity and an excellent antihyperglycemic effect.
摘要:
A DPP-4 inhibitor comprising a peptide represented by the formula (1): Xe-Pro/Ala/Hyp-Xa-Xb-Xc-Xd (SEQ ID NO: 16) (wherein Xe is an amino acid residue with an isoelectric point of 5.9 to 6.3; Pro/Ala/Hyp represents Pro, Ala, or Hyp; Xa is an amino acid residue other than Hyp, Pro, and Arg, or deletion; 5 Xb is Gly, Pro, or deletion; Xc is Pro, Ala, or deletion; and Xd is an amino acid residue or deletion) as an active component. The inhibitor can be expected to bring out an effect of lowering blood glucose levels by enhancing effects of incretins; and the inhibitor may be used as a therapeutic agent for diabetes and, in addition, can act on the immune system or the like to be thus used in 10 treatment for skin diseases or the like.

摘要:
Recombinant collagenases with a stable specific activity and enzyme agents for cell and tissue dissociation such a recombinant are provided. The recombinant collagenase is derived from Grimontia hollisae-derived collagenase is characterized by having, from the N terminus to the C terminus, a collagenase catalytic domain, a linker region sequence, and a prepeptidase C terminal domain, which Grimontia hollisae-derived recombinant collagenase does not comprise at least the prepeptidase C terminal domain. The obtained recombinant collagenase has a high and stable specific activity.
