Description The enzyme, a-mammsidase and the lectin, concanavalin A, both of which interact with a-o-mannosides, are
present in substantial amounts in the mature seeds of Cannualia ensifotmis. The changes in the levels of these two
proteinsand their mRNA have been followed throughout seed development. Although both proteins start appearing in
the seeds at day 24 after pod formation, there is a difference in the developmental patterns. While the increase in the
activity of a-mannosidase is gradual and continues up until about day 44 followed by a slow phase till the desiccation
stage, Con A after a lag phase which lasts to about day 30 shows a logarithmic increase up to about the 36th day followed
by a plateau thereafter upto the desiccation stage. The highest amounts of functional mRNA for these two proteins are
found at the early stages of seed development, well ahead of the period of highest protein deposition, thereby indicating
that post-translational modifications of these proteins are slow and distinct from those of other legumes.
