The subject of the present review is the structural diversity and abundance of cell wall teichuronic and teichulosonic acids of representatives of the order Actinomycetales. Recently found teichulosonic acids are a new class of natural glycopolymers with ald-2-ulosonic acid residues: Kdn (3-deoxy-D-glycero-D-galacto-non-2-ulosonic acid) or di-N-acyl derivatives of Pse (5,7-diamino-3,5,7,9-tetradeoxy-L-glycero-L-manno-non-2-ulosonic or pseudaminic acid) as the obligatory component. The structures of teichuronic and teichulosonic acids are presented. Data are summarized on the occurrence of the glycopolymers of different nature in the cell wall of the studied actinomycetes. The biological role of the glycopolymers and their possible taxonomic implication are discussed. The comprehensive tables given in the Supplement show (13)C NMR spectroscopic data of teichuronic and teichulosonic acids obtained by the authors.
本次综述的主题是放线菌目代表物细胞壁的 teichuronic 和 teichulosonic 酸的结构多样性和丰度。最近发现的 teichulosonic 酸是一类具有 ald-2-ulosonic 酸残基的新型天然糖聚合物：Kdn（3-脱氧-D-甘油-D-半乳糖-壬-2-ulosonic 酸）或 Pse（5,7-二氨基-3,5,7,9-四脱氧-L-甘油-L-甘露诺-2-ulosonic 或 pseudaminic 酸）的二-N-酰基衍生物是必需成分。本文介绍了 teichuronic 和 teichulosonic 酸的结构。总结了研究放线菌细胞壁中不同性质糖聚合物的存在情况。讨论了糖聚合物的生物学作用及其可能的分类学意义。补充材料中给出的综合表格显示了作者获得的 teichuronic 和 teichulosonic 酸的 (13)C NMR 光谱数据。
