摘要:
A process for producing a muturation bone morphogenetic protein by the action of a processing enzyme on a bone morphogenetic protein precursor, which comprisis either introducing an expression vector of a bone morphogenetic protein precursor and an expression vector of a processing enzyme into an animal cell strains, culturing the resultant strain to yield a maturation bone morphogenietc protein, and separating the same from the culture, or alternatively adding a solution of a processing enzyme to a solution of a bone morphogenetic protein precursor and incubating the obtained solution mixture. A suitable process comprises introducing an expression vector of a human MP52 precusor and an expression vector of a secretory furin variant into an established animal cell strain, culturing the resultant strain to yield a muturation bone morphogenetic protein, and separating the same from the culture.
