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.
