The α2 phosphorylase isoenzyme of Oscillatoria princeps, Rhodymenia pertusa and Chlorella pyrcnoidosa has been found to be capable of the synthesis of amylose‐like polyglucans without the necessity for addition of primers. This enzyme differs in this respect from the a1 isoenzyme of blue‐green and green algae. The a2 enzyme appears to be a glyco‐protein and synthesis of linear polyglucans appears to occur by the apposition of glucosyl residues from glucose‐1‐phos‐phate directly to the glycosyl moiety of its molecule.
