Beyond BLASTing : ribonucleoprotein evolution via structural prediction and ancestral sequence reconstruction [PDF]

open access: yes, 2016
Primary homology in DNA and protein sequence has long been used to infer a relationship between similar sequences. However gene sequence, and thus protein sequence, can change over time.

The presence of plasmenyl ether lipids in Capsaspora owczarzaki suggests a premetazoan origin of plasmalogen biosynthesis in animals

open access: yesHeliyon
Plasmalogens are glycerophospholipids with a vinyl ether bond, rather than an ester bond, at sn-1 position. These lipids were described in anaerobic bacteria, myxobacteria, animals and some protists, but not in plants or fungi.
