Crude and alkali-purified fractions of scales isolated from the haptophycean alga Pleurochrysis scherffelii Pringsheim were analyzed. The predominantly cellulosic nature of the fibrillar, alkali-resistent polysaccharide component has been confirmed by gas chromatography of the hydrolysate, by X-ray diffraction and by viscosimetric studies using the nitrified product. Peptide material is covalently linked to this cellulosic structural polysaccharide and remains associated with it through the harsh purification treatments. The amino acid composition of this peptide moiety is given. The relationship of this cellulosic "glycoprotein" to other cell wall glycoproteins is discussed and possible functions during the formation and secretion of wall materials are hypothesized.
对来自甲藻的鳞片的粗提物和碱纯化产物进行了分析。通过水解产物的气相色谱分析、X 射线衍射分析和硝化产物的粘度研究，证实了纤维状、耐碱的多糖成分主要是纤维素。肽物质与这种纤维素结构多糖共价结合，并通过苛刻的纯化处理与之保持关联。给出了该肽部分的氨基酸组成。讨论了这种纤维素“糖蛋白”与其他细胞壁糖蛋白的关系，并假设了它在细胞壁物质形成和分泌过程中的可能功能。
