hi all I'm new to this list, and a complete newbie when it comes to protein visualisation, so I hope this question is ok. I'm looking for a way to convert a fasta sequence of amino acids into a picture of a protein. I've used various sites on thei web, but all of them used a blast like search to tell my proteins which were similar to my fasta sequence, and gave me their structure. I don't mind if the representation isn't accurate, because I'm more interested in whether a change in part of the sequence will have an effect on the final shape. So I don't need great accuracy, just a rough shape. I'm pretty sure that this ab-initio kind of protein visualisation isn't yet possible with just one computer, but maybe somebody could point me in the right direction. thanks Phil P.
