Cofactor: Evidence: Note:
Zn(2+) ECO:0000269 | PubMed:17239391
Activity of protease NS2 is dependent on zinc ions and completely inhibited by EDTA. This is probably due to the fact that NS2 protease activity needs NS3 N-terminus that binds a zinc atom (active region NS2-3).
Mg(2+) ECO:0000269 | PubMed:17239391
ECO:0000250 | UniProtKB:Q9WMX2
Binds 1 zinc ion, which has a structural role (PubMed:17239391). The magnesium ion is essential for the helicase activity (By similarity).
Mg(2+) ECO:0000250 | UniProtKB:P26663
Binds 2 magnesium ion that constitute a dinuclear catalytic metal center.
