Show signal peptides in protein diagrams #356

Closed eweitz closed 1 year ago

This draws signal peptides in proteins. It fills in biological detail that was conspicuously missing with #355.

Like most other sequence features in Ideogram.js, signal peptide data comes from Ensembl. They predicted it with SignalP. In addition to this new feature, existing protein features are now more comprehensive, more distinguishing, and have more coherent colors.

Before

Start of protein looks like other featureless protein regions:

After

Short feature at N-terminal (start of protein, at left) clearly conveys the signal peptide:
