<p>I want to get all the mRNA or protein sequences in a specific pathway, e.g. glycolysis or oxidative phosphorylation, from fruitfly. Is there a convenient way to attain this goal? </p>

<p>I first thought of KEGG database; however, KEGG pathway does not possess pathways specific for fruitfly. (It seems that kegg pathway only has specific pathways for vertebrates.)</p>

<p>Then I turned to FlyBase and found QueryBuilder help a bit.But I am not sure whether I got all genes and no extra in <a href="http://www.genome.jp/kegg-bin/show_pathway?map00190">oxidative phosphorylation</a> for fruitfly by setting the controlled vocabularies to be "oxidative phosphorylation".</p>

<p>I also tried <a href="http://www.biomart.org/">BioMart</a> and failed, because I am not familiar with it. I hope that someone shows me how to do it if BioMart is the right choice.</p>

<p>If there are other tools that can do this job, I would like to try.</p>

<p>Many thanks!</p>
