Description

IPR016363 is a Legume lectin.

<p>This group represents L-type lectins from plants, including leukoagglutinins which bind sialic acid [[cite:PUB00083239]].</p> <p>Lectins are carbohydrate-binding proteins. Leguminous lectins form one of the largest lectin families and resemble each other in their physicochemical properties, though they differ in their carbohydrate specificities. They bind either glucose/mannose or galactose [[cite:PUB00001507]]. Carbohydrate-binding activity depends on the simultaneous presence of both a calcium and a transition metal ion [[cite:PUB00046607]]. The exact function of legume lectins is not known, but they may be involved in the attachment of nitrogen-fixing bacteria to legumes and in the protection against pathogens [[cite:PUB00057387], [cite:PUB00057388]].</p> <p>Some legume lectins are proteolytically processed to produce two chains, beta (which corresponds to the N-terminal) and alpha (C-terminal) [[cite:PUB00057390]]. The lectin concanavalin A (conA) from jack bean is exceptional in that the two chains are transposed and ligated (by formation of a new peptide bond). The N terminus of mature conA thus corresponds to that of the alpha chain and the C terminus to the beta chain [[cite:PUB00057389]]. Though the legume lectins monomer is structurally well conserved, their quaternary structures vary widely [[cite:PUB00046607]].</p>
