ATPase p97 + H2O

?
a cofactor-binding motif of p97 contained within the last 10 amino acid residues of the C terminus is both necessary and sufficient to mediate interactions of p97 with PNGase. Phosphorylation of p97Ć¢ĀĀs highly conserved penultimate tyrosine residue, which is the main phosphorylation site during T cell receptor stimulation, completely blocks binding of either PNGase or Ufd3 to p97. This observation suggests that phosphorylation of this residue modulates endoplasmic reticulum-associated protein degradation activity by discharging substrate-processing cofactors

heat-denatured RNase B and lactoferrin are almost completely deglycosylated by PNGaseH+, profiles of N-glycan products released from the substrates, similar to PNGase F, overview. The acidic enzyme, termed PNGase H+, shows an extremely low pH optimum with a broad substrate specificity. The recombinant PNGase H+ can liberate high mannose-, hybrid- and complex-type N-glycans including core alpha1,3-fucosylated oligosaccharides from both glycoproteins and glycopeptides. PNGase H+ exhibits a better release efficiency over N-glycans without core alpha1,3-fucose compared with PNGase A

ATPase p97 + H2O
?
a cofactor-binding motif of p97 contained within the last 10 amino acid residues of the C terminus is both necessary and sufficient to mediate interactions of p97 with PNGase. Phosphorylation of p97Ć¢ĀĀs highly conserved penultimate tyrosine residue, which is the main phosphorylation site during T cell receptor stimulation, completely blocks binding of either PNGase or Ufd3 to p97. This observation suggests that phosphorylation of this residue modulates endoplasmic reticulum-associated protein degradation activity by discharging substrate-processing cofactors
