| Abstract: | Isolation of the cytoplasmic and thylakoid membranes, and cell walls of Anabaena 7120 and analysis of the features of their pigments and proteins were studied during 1987-1989. The cytoplasmic and thylakoid membranes of Anabacna 7120 were isolated by mechanical disruption of the vegetative cells followed by discontinuous sucrose density gradient centrifugation. The cell walls of Anabaena 7120 were obtained by the Triton X-100 treatment method. The features of pigments and proteins of cytoplasmic and thylakoid membranes of Anabaena 7120 were similar to those of unicellular blue-green algae. The Triton-insoluble cell wall of Anabaena 7120 had no spectral absorption in visible light. Its SDS-PAGE map showed two major polypeptide bands with apparent MW. of 52KD and 14KD and both of them were glycoproteins. 14KD was peptidoglycan-associated protein. Almost all of the cell wall proteins were sensitive to trypsin treatment. The "heat-modifiable protein" was not found in the cell walls of Anabaena 7120. |
