We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Arcelin-1 is a glycoprotein from kidney beans (Phaseolus vulgaris) which displays insecticidal properties and protects the seeds from predation by larvae of various bruchids. This lectin-like protein is devoid of monosaccharide binding properties and belongs to the phytohemagglutinin protein family. The x-ray structure determination at 1.9-A resolution of native arcelin-1 dimers, which correspond to the functional state of the protein in solution, was solved using multiple isomorphous replacement and refined to a crystallographic R factor of 0.208. The three glycosylation sites on each monomer are all covalently modified. One of these oligosaccharide chains provides interactions with protein atoms at the dimer interface, and another one may act by preventing the formation of higher oligomeric species in the arcelin variants. The dimeric structure and the severe alteration of the monosaccharide binding site in arcelin-1 correlate with the hemagglutinating properties of the protein, which are unaffected by simple sugars and sugar derivatives. Sequence analysis and structure comparisons of arcelin-1 with the other insecticidal proteins from kidney beans, arcelin-5, and alpha-amylase inhibitor and with legume lectins, yield insights into the molecular basis of the different biological functions of these proteins.
