Bioinformatics with Python Cookbook - Second Edition

Finding orthologues with the Ensembl REST API

Here, we will examine how to look for orthologues for a certain gene. This simple recipe will not only introduce orthology retrieval, but also how to use REST APIs on the web to access biological data. Last, but surely not least, it will serve as an introduction on how to access the Ensembl database using the programmatic API.

In our example, we will try to find any orthologue for the human lactase (LCT) gene on the horse genome.
