Cell Wall Glycopolymers as a Diagnostic Trait of Arthrobacter crystallopoietes
Mikrobiologiia = Microbiology [Russian] 91(3) (2022)
259-266
The composition and structure of the cell wall glycopolymers from Arthrobacter crystallopoietes VKM Ac-1107T (family Micrococcaceae, phylum Actinobacteria), previously assigned to the “A. globiformis” group based on the high similarity of 16S rRNA gene sequences and traditional chemotaxonomic markers were studied. Teichoic acid—1,3-poly(glycerol phosphate) substituted with β-glucose residues, and diglycosyl 1-phosphate polymer with -6)-α-D-GalpNAc-(1→6)-α-D-GlcpNAc-(1-P-repeating unit were identified by chemical and NMR spectroscopy methods. The results of phylogenomic (taxogenomic) analysis, viz. determination of the average amino acid identity (AAI) and the similarity of conserved proteins (POCP), indicate that A. crystallopoietes belongs to a new genus and the composition of the cell wall glycopolymers may serve as a diagnostic characteristic of this genus, which will be described on the basis of A. crystallopoietes.
