substrate-binding cleft pattern of SaPth, the cleft is conservatively composed of three segments, namely, a base loop (Gly106-Gly113 in SaPth), a gate loop (Leu89-Val100 in SaPth), and a lid loop (Gly134-Gln148 in SaPth). The base loop constitutes one side of the cleft, and the gate loop and lid loop form the other side of the cleft. A structural comparison among all of the substrate-free structures in Pths reveals three different states of substrate-binding clefts; one state is the closed state (the substrate-binding cleft is closed at both the lid and gate loops, such as in SpPth), the second is the semi-closure state (the substrate-binding cleft is closed at the gate loop but wide-open at the lid loop, such as in MtPth and MsPth), and the third is the open state (the substrate-binding cleft is wide-open when both the lid and gate loops are away from the base loop)

metabolism
enzyme Vms1, which contains a Cdc48-binding VIM motif, is implicated in the ribosome quality control (RQC) pathway. The 60S subunits retain the peptidyl-tRNA nascent chains, which recruit the RQC complex comprised of Rqc1-Rqc2-Ltn1-Cdc48-Ufd1-Npl4. Nascent chains ubiquitylated by the E3/ubiquitin ligase Ltn1 are extracted from the 60S by the ATPase Cdc48-Ufd1-Npl4 and presented to the 26S proteasome for degradation. The Vms1-dependent reaction does not display strong dependence on substrate ubiquitylation

bacterial peptidyl-tRNA hydrolase (Pth) is an essential enzyme that alleviates tRNA starvation by recycling prematurely dissociated peptidyl-tRNAs. Pth performs the essential function of hydrolyzing the peptidyl-tRNAs released in the cytoplasm because of premature termination of translation. Hydrolysis of the substrate is achieved by the coordinated action of highly conserved residues N14, H24, D97, and N118
physiological function
bacterial peptidyl-tRNA hydrolase hydrolyzes the peptidyl-tRNAs accumulated in the cytoplasm and thereby preventing cell death by alleviating tRNA starvation
physiological function
peptidyl-tRNA hydrolase (Pth) catalyzes the breakdown of peptidyl-tRNA into peptide and tRNA components. Pth is an esterase and cleaves the peptidyl-tRNA molecules at the ester bond between the tRNA and the peptide and generates tRNA and peptide components to ensure continuous supply of the required raw material in terms of tRNA and amino acids. This allows the continuity of the essential protein biosynthetic process. Thus, Pth plays a crucial role in the regulation of protein synthesis in the cell

role of Met71 in substrate recognition and structural integrity of bacterial peptidyl-tRNA hydrolase. The interactions of M71 with N14 and H24 play an important role in optimal positioning of their side-chains relative to the peptidyl-tRNA substrate. These interactions of M71 are important for the activity, stability, and compactness of the protein. Molecular dynamics simulation of M71A mutant in comparison to wild-type, overview
additional information
the activity and selectivity of the protein depends on the stereochemistry and dynamics of residues H24, D97, N118, and N14. D97-H24 interaction is critical for activity because it increases the nucleophilicity of H24. The N118 and N14 have orthogonally competing interactions with H24, both of which reduce the nucleophilicity of H24 and are likely to be offset by positioning of a peptidyl-tRNA substrate. The region proximal to H24 and the lid region exhibit slow motions that may assist in accommodating the substrate. Helix alpha3 exhibits a slow wobble with intermediate time scale motions of its N-cap residue N118, which may work as a flypaper to position the scissile ester bond of the substrate. The dynamics of interactions between the side chains of N14, H24, D97, and N118, control the catalysis of substrate by this enzyme, structure-function analysis, overview. The catalytic site resides in a crevice on the surface of the protein, active site structure analysis, NMR and molecular dynamics simulation study for structure modelling

in the M71A mutant structure, chain A residues N14, P15, E18, Y19, H24, P46, T68-L73, K76, N118, V149, A150, V153, L154 are involved in interfacial interaction. While for chain B, the interfacial residues are L101-V105, K107-K109, R137, H142-G144, C164, and H192-E197. This indicates that the interface is formed between the active site of chain A and the C-terminal of chain B. The intermolecular bonding network for the M71A mutant is completely different from wild-type enzyme VcPth. In the M71A mutant structure, the interface has 8 hydrogen bonds, 2 salt bridges and 6 hydrophobic interactions. The three hydrogen bonds that stabilize the interface are formed by strictly conserved residues involved in the enzyme catalysis, i.e. N and ND2 atoms of N72 with the O atoms of K195 and E197, respectively

D97N
site-directed mutagenesis, the catalytically important hydrogen bond between D97 and H24 is lost after the mutation and a new H-bond is formed between H24 and N118
H24N
site-directed mutagenesis, the amide group of N24 partially occupies the site of the original histidine ring. The salt bridge between H24 and D97, which is conserved in all other canonical Pth structures, is lost in the H24N mutant structure of VcPth. N24 forms a hydrogen bond with D97, and a new hydrogen bond is also formed between N14 and N24. Hydrophobic interactions of H24 with M71 and V153 are lost upon H24N mutation
M71A

While for chain B, the interfacial residues are L101-V105, K107-K109, R137, H142-G144, C164, and H192-E197. This indicates that the interface is formed between the active site of chain A and the C-terminal of chain B. The intermolecular bonding network for the M71A mutant is completely different from wild-type enzyme VcPth. In the M71A mutant structure, the interface has 8 hydrogen bonds, 2 salt bridges and 6 hydrophobic interactions
N118D
site-directed mutagenesis, the N118D crystal structure shows a change in the side-chain orientation of D118, which results in the formation of a new hydrogen bond between NE2 of H24 and OD1 of D118 after the mutation
N14D
site-directed mutagenesis, backbone amide resonances for D14 and D147 cannot be assigned for the N14D mutant, loss of the conserved hydrogen bond between OD1 of N14 and N of M71, but the reciprocatory hydrogen bonding between N14 and N25, which is observed in wild-type VcPth, is conserved in the N14D mutant
