Acidic water stress polypeptides (Wsp) with molecular masses of 33, 37 and 39 kDa are the most abundant soluble proteins in the cyanobacterium Nostoc commune. Wsp polypeptides and UV-A/B-absorbing pigments are secreted by cells, accumulate in the extracellular glycan sheath, and are released from de...
