POSTTRANSLATIONAL MODIFICATION
ORGANISM
UNIPROT
COMMENTARY
LITERATURE
proteolytic modification
proteolytic modification
-
the enzyme has a C-terminal propeptide of 1000 Da that contains an endoplasmic reticulum retention signal, KDEL. The KDEL-tail functions to store SH-EP as a transient zymogen in the lumen of the ER, and the C-terminal propeptide is thought to be removed within the ER or immediately after exit from the ER
proteolytic modification
-
the enzyme is synthesized on membrane-bound ribosomes as an inactive 45000 Da precursor, which is cotranslationally processed to a 43000 Da intermediate through cleavage of the signal sequence. The 43000 Da intermediate of SH-EP is further processed to the 33000 Da mature enzyme via 39000 Da and 36000 Da intermediates
proteolytic modification
-
the N-terminal post-translational processing of SH-EP is mediated by at least two processing enzymes, designated VmPE-1 and VmPE-2
