title: [A natural fluorescent protein that changes its fluorescence during maturation].
abstract: The gene of a new red fluorescent protein zoan2RFP from a coral polyp Zoanthus sp., a homologue of the known green fluorescent protein from the Aequorea victoria jellyfish, was cloned. At early maturation stages, zoan2RFP exhibits a green fluorescence, which then turns into the red one. A similar phenomenon was recently reported for the E5 mutant of the red fluorescent coral protein DsRed. Zoan2RFP differs from E5 by faster maturation kinetics and the complete disappearance of green fluorescence in the mature protein. Naturally occurring proteins of this type can be considered as intermediate forms between the green and red fluorescent proteins, which are formed during the microevolution of fluorescent proteins.
