4.4.1.30	physiological function	cpcT null mutant contains 40% less phycocyanin than wild type and produces smaller phycobilisomes with red-shifted absorbance and fluorescence emission maxima. Phycocyanin from the cpcT mutant has an absorbance maximum at 634 nm compared with 626 nm for the wild-type. The phycocyanin beta-subunit from the cpcT mutant has slightly smaller apparent molecular weight on SDS-PAGE. No phycocyanobilin chromophore is bound to the peptide containing Cys153 derived from the phycocyanin beta-subunit of the cpcT mutant	732027	
4.4.1.30	physiological function	enzyme specifically binds phycoerythrobilin in vitro leading to a tight complex. The complex is not directly able to transfer phycoerythrobilin to the host phycobiliprotein beta-subunit. However, it can assist the host lyase CpeS in its function	748222
