Sphere-Rod Morphogenesis in Arthrobacter crystallopoietes I. Cell Wall Composition and Polysaccharides of the Peptidoglycan1
AUTOR(ES)
Krulwich, Terry A.
RESUMO
Cell walls of Arthrobacter crystallopoietes were prepared from cells grown as spheres and from peptone- and succinate-induced rod stage cells. Undegraded polysaccharide backbones of the peptidoglycans were isolated from myxobacter AL-1 protease digests by ECTEOLA cellulose and Sephadex G-50 chromatography. The polysaccharide backbones of the sphere cell wall peptidoglycan are heterogeneous in their size, and average less than 40 hexosamines per chain. Those of the rod cell walls are homogeneous in size and average 114 to 135 hexosamines per chain.
