Uncharacterized protein annotation from plant

Question

[mriaz]

i have list of uncharacterized protein from plant source. the list is so big and difficult to do it manually. is there any software which can annotate these protein database automatically on the basis of function? thanks

some more background info might be useful here.

So you are looking to functionally annotate (== add some function label to them) your predicted proteins?
