"The
persistent interaction between E173 of Cez2 and K33 of the substrate
suggests that this is an important factor to stabilize the proximal
Ub–Cez2 binding.Thus, for the third catalytic site residue E173, a similar dual
functional role as for Cez can be suggested: it is critical for the
recognition and stabilization of proximal Ub binding to Cez2 (for
Cez2 Ub : 61% of the simulation time, for Cez2 Ub : 52%) and the stabilization of the
Cys/His dyad by a water-mediated interaction with H367 as E173 makes
a water bridge for ≥90% of the simulation time."
