3.7.1.4 glycoprotein - 749964 3.7.1.4 glycoprotein mannose-rich, complex glycosylated mature enzyme, dependent on ooptimal folding of the processed proform in presence of the pro-peptide 656110 3.7.1.4 proteolytic modification enzyme is sythesized as a transport-competent precursor, i.e. pro-LPH, intracellular cleavage process in the trans-Golgi network between Arg734 and Leu 735 to yield the mature enzyme, i.e. LPHbetainitial, the propeptide of the zymogen, i.e. LPHalpha, modulates as a chaperone the folding of the mature enzyme after it has been cleaved off, mechanism, overview 656110
