additional information
?
-
the enzyme specifically binds bilins with a reduced 15,16-double bond. The complex with phycoerythrobilin is highly stable and displays a strong red fluorescence. CpeT does not transfer phycoerythrobilin to the host phycobiliprotein beta-subunit but is able to assist the host layse
