Abstract
The water-soluble antenna chromoprotein phycocyanin-645 from a Chroomonas species (Cryptophyceae) has been crystallized. X-ray precession photographs prove space groups P3121 (or the enantiomorphic P3221) for the trigonal and P212121 for the orthorhombic crystals. Density measurements indicate that the asymmetric units of these crystals contain three or two heterotetrameric units (αάβ2), respectively. The packing of both crystal forms is quite different to that of any other crystals reported so far for phycobiliproteins of blue-green and red algae. The cationic detergent benzalkonium chloride (BAC) is strongly bound in the crystals. Both observations indicate a considerable membrane affinity and a unique association behaviour of the phycobiliproteins from cryptomonads.
