Unraveling and characterization of novel T3SS effectors in Edwardsiella piscicida
ABSTRACT Type III secretion system (T3SS) facilitates survival and replication of Edwardsiella piscicida in vivo . Identifying novel T3SS effectors and elucidating their functions are critical in understanding the pathogenesis of E. piscicida. E.

Unprecedented Protein Divergence Within a T3SS Family [PDF]
Selection pressure drives rapid emergence of antibiotic resistance mechanisms promoting searches for therapeutic targets in bacterial processes needed for virulence, not viability, which include the Type Three Secretion System (T3SS). Distinct T3SS families evolved from the flagellar export apparatus where remaining homology hinders development of anti-

Quorum sensing employs a dual regulatory mechanism to repress T3SS gene expression
ABSTRACT The type III secretion system (T3SS) is a needle-like complex used by numerous bacterial pathogens in host infection to inject exotoxins into the host cell cytoplasm.

Characterization of Virulence Function of Avirulence Protein E1 (AvrE1) during Host Plant Infection [PDF]
Pseudomonas cichorii secretes effectors that suppress defense mechanisms in host plants. However, the function of these effectors, including avirulence protein E1 (AvrE1), in the pathogenicity of P. cichorii, remains unexplored.

An intra-bacterial activity for a T3SS effector [PDF]
Abstract Many Gram-negative bacterial pathogens interact with mammalian cells by using type III secretion systems (T3SS) to inject virulence proteins into host cells. A subset of these injected protein ‘effectors’ are enzymes that inhibit the function of host proteins by catalyzing the addition of unusual post ...

Molecular Targets and Strategies for Inhibition of the Bacterial Type III Secretion System (T3SS); Inhibitors Directly Binding to T3SS Components [PDF]
The type III secretion system (T3SS) is a virulence apparatus used by many Gram-negative pathogenic bacteria to cause infections. Pathogens utilizing a T3SS are responsible for millions of infections yearly. Since many T3SS knockout strains are incapable of causing systemic infection, the T3SS has emerged as an attractive anti-virulence target for ...

The T3SS Effector Protease NleC Is Active within Citrobacter rodentium [PDF]
Whether type III secretion system (T3SS) effector proteins encoded by Gram-negative bacterial pathogens have intra-bacterial activities is an important and emerging area of investigation. Gram-negative bacteria interact with their mammalian hosts by using secretion systems to inject virulence proteins directly into infected host cells.

HrpS Is a Global Regulator on Type III Secretion System (T3SS) and Non-T3SS Genes in Pseudomonas savastanoi pv. phaseolicola [PDF]
The type III secretion system (T3SS) is the main machinery for Pseudomonas savastanoi and other gram-negative bacteria to invade plant cells. HrpR and HrpS form a hetero-hexamer, which activates the expression of HrpL, which induces all T3SS genes by binding to a ‘hrp box’ in promoters.

Autoinducer-2 and bile salts induce c-di-GMP synthesis to repress the T3SS via a T3SS chaperone
Abstract Cyclic di-GMP (c-di-GMP) transduces extracellular stimuli into intracellular responses, coordinating a plethora of important biological processes. Low levels of c-di-GMP are often associated with highly virulent behavior that depends on the type III secretion system (T3SS) effectors encoded, whereas ...
