Cyanophora paradoxa

Interestingly an erythrin, without the C-terminal rubredoxin domain is found, perhaps appropriately in Cyanophora paradoxa, where, like the rubrerythrins, its function is unknown.

The peptidoglycan isolated from the photosynthetic organelles of Cyanophora paradoxa contains 2-acetamido-2-deoxy-D-glucose, A-acetylmu ramie acid, L-alanine, L-glutamic acid, and diaminopimelic acid (1 1 1.6 1 1) and may be present as a lipoprotein-peptidoglycan complex.Close similarities to the structures of other Gram-negative bacteria and cyanobacteria were observed.
