Terminal elongation of microtubes (sheaths) which are extracellulary produced by filamentous ion-oxidizing bacteria, Sphaerotilus natans and Leptothrix cholodnii, was confirmed by fluorescent microscopy. The sheaths were revealedto be commonly assembled from thiolic glycoconjugates composed of amphoteric glycan coreand dipeptide side chain containing glycine and cysteine. Considering their uniquechemical structures, the sheath-forming thiolic glycoconjugates were proposed to becollectively termed thiopeptidoglucan.
