Marc,
There is a WWW site that has sequences for many different vectors. There
is a section just for yeast plasmids.
here is the URL for the vector database:
http://biology.queensu.ca/~miseners/vector.html
Go there, then to the section for yeast plasmids. Find the one you want, and
there should be links to sequence and also major Database links.
Good Luck,
