Abstract:

An antitumour lectin named AAL has been purified from the fruiting body of edible mushroom Agrocybe aegerita. In addition to having a distinct bioactivity, AAL shows strong inhibition effects on human and mouse tumour cells. It has been shown that AAL exerts its antitumour effects via apoptosis-induction. AAL and AAL-lactose complex have been crystallized and their diffraction data were collected with resolution of 2.6 Å and 3.0 Å, respectively. Both crystals belong to space group P 6122 with unit cell parameters a = 123.98 Å, b = 123.98 Å, c = 56.86 Å, a= b=90 , g = 120 and a = 123.69 Å, b = 123.69 Å, c = 56.64 Å, α= β=90 , γ = 120 , respectively.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
