3.5.1.122 | more |
dual specificity of yeast Nta1 (yNta1), importance of second-position residues in Asn/Gln-bearing N-terminal degradation signals (N-degrons), also cf. EC 3.5.1.121. Specific hydrogen bonds stabilize interactions between N-degron peptides and hydrophobic peripheral regions of the active site pocket, interactions between Nta1 and N-degron peptides, detailed overview. The enzyme shows glutamine-specific enzyme activity with dipeptides Gln-Val and Gln-Gly, Michaelis-Menten kinetics |
