[Enzymatic cleavage of human neurophysin into 2 sub-domains containing 3 and 4 disulfides].
Native human MSEL-neurophysin has been subjected to trypsin hydrolysis. Because of a change of the bond Lys59-Pro60 found in other mammalian neurophysins into Lys59-Ala60 in human protein, a peculiar cleavage has occurred in the latter, leading to a split of the molecule into two halves. The N-terminal sub-domain contains 4 disulfide bridges whereas the C-terminal one possesses 3 disulfide bridges.
