Virulence of Agrobacterium tumefaciens requires phosphatidylcholine in the bacterial membrane.
Phosphatidylcholine (PC, lecithin) has long been considered a solely eukaryotic membrane lipid. Only a minority of all bacteria is able to synthesize PC. The plant-transforming bacterium Agrobacterium tumefaciens encodes two potential PC forming enzymes, a phospholipid N-methyltransferase (PmtA) and a PC synthase (Pcs). We show that PC biosynthesis and tumour formation on Kalanchoë plants was i...
متن کاملA Bilayer-Couple Model of Bacterial Outer Membrane Vesicle Biogenesis
UNLABELLED Gram-negative bacteria naturally produce outer membrane vesicles (OMVs) that arise through bulging and pinching off of the outer membrane. OMVs have several biological functions for bacteria, most notably as trafficking vehicles for toxins, antimicrobials, and signaling molecules. While their biological roles are now appreciated, the mechanism of OMV formation has not been fully eluc...
متن کاملDe novo synthesis of bacterial glycogen: Agrobacterium tumefaciens glycogen synthase is involved in glucan initiation and elongation.
Evidence is presented indicating that initiation of glycogen synthesis in Agrobacterium tumefaciens does not require the presence of alpha(1,4)-linked glucans. Crude cell extracts incubated with ADP-glucose (Glc) were able to form alpha(1,4)-linked glucans despite the fact that cells used for extract preparation displayed a genotype that prevented synthesis of Glc-containing sugar nucleotides a...
متن کاملRcsF is an outer membrane lipoprotein involved in the RcsCDB phosphorelay signaling pathway in Escherichia coli.
The RcsCDB signal transduction system is an atypical His-Asp phosphorelay conserved in gamma-proteobacteria. Besides the three proteins directly involved in the phosphorelay, two proteins modulate the activity of the system. One is RcsA, which can stimulate the activity of the response regulator RcsB independently of the phosphorelay to regulate a subset of RcsB targets. The other is RcsF, a pu...
متن کاملAgrobacterium tumefaciens mutants affected in attachment to plant cells.
An analysis of Agrobacterium tumefaciens mutants with Tn5 insertions in chromosomal DNA showed that the chromosome of A. tumefaciens codes for a specific ability of this bacterium to attach to plant cells. This ability is associated with tumorigenesis by A. tumefaciens, the ability of avirulent A. tumefaciens to inhibit tumorigenesis, and the ability to adsorb certain phages. A second class of ...
