 Title    Oxygen-Evolving Extracts from a Thermophilic Cyanobacterium Synechococcus sp  
 Abstract    Spheroplast membranes o f a thermophilic cyanobacterium Synechococcus sp. have been treated with the detergent lauryldim ethylam ine oxide (LD A O). The resulting extracts show (1) light-induced 0 2 evolution with artificial electron acceptors, (2) four-fold enhancement o f the 0 2 evolution relative to chlorophyll, (3) parallel increase o f both the molar ratios o f PS 2/C hl and cyt b559/C hl in the extract, (4) dissociation o f the auxiliary pigm ent phycocyanin upon treatment with LDAO, but still tight association o f allophycocyanin to the photosystem 2 preparation.

 Title    Reconstitution of an Allophycocyanin Trimer Complex Containing the C-Terminal 2 1 -2 3 kDa Domain of the Core-Membrane Linker Polypeptide Lcm  
 Abstract    Allophycocyanin (AP) was isolated from extracts of the cyanobacterium Mastigocladus laminosus. A fraction enriched in AP-associated polypeptides with apparent molecular masses of 2 1 -2 3 kD a in SDS-PAGE, was isolated on a preparative scale and identified as a hom olo­ gous mixture of C-terminal fragments o f the core-membrane linker polypeptide Lcm. The com ­ plex (aAPßAP)3-21 -2 3 kD a was reconstituted and characterized by sucrose density gradient ultracentrifugation, absorption, fluorescence emission and circular dichroism spectroscopy. The 2 1 -2 3 kD a polypeptides were found to induce spectral changes in AP similar to those induced by the small core linker polypeptide Lc8 9. Possible functions of the complex in phy-cobilisomes are discussed.

 Title    Der Einfluß von Cycloheximid und Chloramphenicol auf die Biosynthese der Photosynthese-Pigmente in Cyanophora paradoxa Korsch. HI. Chlorophyll a und Phycochromoproteide Chlorophyll a and Phycochrom oproteids  
 Abstract    The Influence o f Cyclohexim ide and C hloram phenicol on the B iosynthesis o f the P hotosynthetic P igm ents in Cyanophora paradoxa. III. The inhibition effects o f CHI and CA on the biosynthesis o f the tetrapyrrolpigments were measured with two methods (in vivo VIS-spectroscopy, for chlorophyll (Chi) and the phyco­ chromoproteids, 14C incorporation only for Chi). In the case o f the Chl-biosynthesis both methods show the sam e results: a) In vivo VIS-spectroscopy demonstrates that the inhibition effect o f CA manifests faster than that o f CHI, b) during the 14C incorporation into Chi chloramphenicol (CA) inhibits more than cyclohexim ide (CHI) in contrary to the behaviour o f chloroplasts. It seems that the CHI caused decrease o f l4C incorporation into Chi can be ascribed to the decreased photosynthesis. The influence o f the antibiotics o f the phycochrom o­ proteids is similar to that observed for chlorophyll. It is remarkable that under the influence o f CHI the phycochromoproteid biosynthesis is significantly better than under CA influence, although CHI damages the consortium more than CA. That can be interpreted, as for chlorophyll, with a more endocytobiont coded phycochrom oproteid synthesis.
