How large is a "large" protein string normally when doing BLAST? Will do searches for protein strings say consisting of 32KB of letters? Is there an upper limit? I suppose there is no real upper limit, but there might be a tendency for proteins to rarely go above a certain length... I am trying to design some hobbyist software in biology and these sort of answers would really help my design. Excuse my lack of biology background! -- http://elfdata.com/plugin/
