Action of lysozyme on penicillin-induced filaments of Proteus vulgaris.
Penicillin-induced filaments of Proteus vulgaris P 18 had a seemingly unaltered cell envelope. Lysozyme, however, reduced the wall part of these filaments into a three-layered structure and caused transformation into spheroplasts. Although cross walls and membrane septa were absent in the filaments, most of the lysozyme-induced spheroplasts remained attached to each other.

15 صفحه اولFurther observations on the motility of proteus vulgaris grown on penicillin agar.
The movement of the enormously enlarged filaments of Proleus vulgaris grown on penicillin agar ceased, or was slowed down, by screening the culture from the radiant heat of a microscope lamp. Organisms stimulated by heat after resting a short time in this way moved more rapidly than before. The increased activity was maintained for longer periods with longer rests, the increment in the period o...
متن کاملPenicillin-binding proteins and carboxypeptidase/transpeptidase activities in Proteus vulgaris P18 and its penicillin-induced stable L-forms.
The originally penicillin-induced, wall-less stable L-forms of Proteus vulgaris P18, isolated by Tulasne in 1949 and since then cultured in he absence of penicillin, have kept the ability to synthesize the seven penicillin-binding proteins and the various DD- and LD-peptidase activities found in the parental bacteria and known to be involved in wall peptidoglycan metabolism. The stable L-forms,...
متن کاملFilaments of Amoeba Proteus
Amoeba proteus has two types of cytoplasmic filaments that are thought to be important in cell motility, cytoplasmic streaming, and changes in cytoplasmic consistency : thin, 50-70 A wide filaments, and short, thick, 160 A wide rods (Pollard and Ito, 1970) . The thin filaments resemble the actin filaments of muscle (Hanson and Lowy, 1963), Acanthamoeba (Weihing and Korn, 1969 ; Pollard et al .,...
