Definition

asx-motif
A motif of five consecutive residues and two H-bonds in which:
 - residue(i) is Aspartate or Asparagine (Asx)
 - side-chain O of residue(i) is H-bonded to the main-chain NH of residue(i+2) or (i+3)
 - main-chain CO of residue(i) is H-bonded to the main-chain NH of residue(i+3) or (i+4)
	
Comments
Most often found at the N-termini of α-helices.
