O. Nishimura et al., AN EFFICIENT CHEMICAL METHOD FOR REMOVING N-TERMINAL EXTRA METHIONINEFROM RECOMBINANT METHIONYLATED HUMAN GROWTH-HORMONE, Chemical communications, (10), 1998, pp. 1135-1136
Conversion of recombinant methionylated human growth hormone (Met-hGH)
into its non-methionylated form (hGH) has been successfully achieved
by a chemical process, which consists of a transamination reaction and
phenylene-1,2-diamine treatment.
