Reliable database for true paralogs

Question

[George X.]

Hello everyone,

I have been struggling to find a database that shows the true paralogs ( I mention "true" beacause some bases present some genes as paralogs that are not truly paralogs), however despite my findings I'm not sure about their reliability. In my case I look for a database that has a wide range of organisms and contains ideally all oxidative phosphorilation genes. Any idea/advise? Thank you in advance!
