Identification and characterization of metal-chelating bioenhancer peptide derived from fermented Citrullus lanatus seed milk.

In the present investigation, a metal-chelating bioactive peptide was derived from Citrullus lanatus seed milk fermented with Lactococcus lactis. The cationic fermented milk peptide (FMP) thus obtained was purified using the HiTrap-chelating column followed by rpHPLC. The FMP possessed the ability to chelate multiple divalent cations like Cu , Ca , and Fe with 86.
