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 asparagine-specific enzyme activity with dipeptides An-Val and Asn-Gly, Michaelis-Menten kinetics |

enzyme PNAD does not act on internal asparagine residues and requires a free Nalpha-amino groups. It has reduced or no activity on NH2-terminal asparagine dipeptides and no activity toward free asparagine or asparagine amide. It does not act on any NH2-terminal glutamine substrates |
