Summary

자동 번역

Om de beperkingen van klassieke site-directed mutagenese te overwinnen, werden proline analogen met specifieke modificaties opgenomen in verschillende fluorescerende eiwitten. We laten zien hoe de vervanging van waterstof door fluor of van de enkele door dubbele bindingen in prolineresiduen ("moleculaire chirurgie") fundamentele eiwiteigenschappen beïnvloedt, inclusief hun vouwing en interactie met licht.
