This enzyme was transferred from E.C. 3.4.99.46 to E.C. 3.4.25.1.
The structure of this enzyme is cylindrical with four layers of seven subunits, composed of 14 different subunits. All the alpha-subunits are enzymatically inactive, whereas three of seven beta-subunits (PRE3, PUP1 & PRE2) exhibit proteolytic activity.
According to the protein names in Swiss-prot, corresponding subunits of these structures seem to be as follows (see [11] & [18]):
These subunits are homologous but different.
beta4 = PSB2_YEAST;P22141 (PRE1 C11)
beta5 = PSB5_YEAST;P30656 (PRE2 DOA3 PRG1) (Catalytic subunit)
beta6 = PSB1_YEAST;P23724 (PRE7 PRS3 PTS1 C5)
beta7 = PSB4_YEAST;P30657 (PRE4)
Chains of PDB entries (above) were grouped in each subunit.
According to the literature [8], [11], [16], [18], [20], [29] & [35], the catalytic reaction probably proceeds as follwos:
(1) Alpha-amino group of Thr1 acts as a general base to activate the nucleophile, sidechain of Thr1, through a water molecule (NUK). At the same time, Lys33, which is modulated by Asp17, might modulate or stabilize the nucleophilicity of Thr1.
(2) Thr1 makes a nucleophilic attack on the carbonyl carbon of the target peptide bond, forming a tetrahedral (hemiacetal) transition-state.
(3) The alpha-amino group of Thr1 acts as a general acid to protonate the leaving group, giving a carbonyl intermediate. The intermediate might be stabilized by an oxyanion hole, composed of the sidechain of Lys33 and mainchain amide of Gly47.
(4) Alpha-amino group of Thr1 acts as a general base to activate the NUK water, which completes hydrolysis.
