Lucas C.

A DFR copy in this species has acquired the same AA substitution in the <a href="https://ecoevo.social/tags/ActiveSite" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ActiveSite</span></a> that contributed to the evolution of enhanced DHK (red pigment precursor) activity in the genus <a href="https://ecoevo.social/tags/Iochroma" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Iochroma</span></a> (Solanaceae). This is the only obvious case of likely functional alteration of enzyme specificity in our dataset.</p>
