Non classical secretion systems
Research in Microbiology, 2013Bacteria use molecular machines or weapons to colonize, invade or fight other bacteria and eukaryotic cells. In addition to these various secretion systems, two different systems that release bacterial compounds have also been described. The first one corresponds to membrane vesicle formation and to long distance delivery of membrane or soluble ...

Coxiella burnetii Secretion Systems
2012The ability of bacteria to transport proteins across their membranes is integral for interaction with their environment. Distinct families of secretion systems mediate bacterial protein secretion. The human pathogen, Coxiella burnetii encodes components of the Sec-dependent secretion pathway, an export system used for type IV pilus assembly, and a ...

Analysis of Type III Secretion System Secreted Proteins
2016Secreted proteins of the T3SS vary from genus to genus. How secretion is induced in vitro also depends on the genus of bacteria. However, once those proteins are isolated the method for analyzing those proteins is largely the same. The following chapter outlines the specific induction of Yersinia secreted proteins and uniform analysis of those secreted

Type VI secretion system baseplate
Nature Microbiology, 2018Bacteria employ a specialized weapon known as the type VI secretion system to defend themselves from competing organisms. A new study reveals the molecular architecture of the type VI secretion system and highlights conserved mechanistic similarities with contractile phage tails.

CryoEM of bacterial secretion systems
Current Opinion in Structural Biology, 2018The need for bacteria to interact with their environment has driven the evolution of elaborate secretion systems. By virtue of their function, secretion systems are macromolecular complexes associated with the cell envelope and therefore inherently difficult to study by conventional structural biology techniques.

Insulin secretion: The effector system
Experientia, 1984Studies of the role of the microtubule-microfilamentous system in insulin secretion have been widened by continuing experimentation and analysis to provide a comprehensive working hypothesis which embraces ideas of the way in which the polymerization of microtubules and microfilaments may be regulated and how these cytoskeletal components may act ...

Genomic analysis of secretion systems
Current Opinion in Microbiology, 2003Secretion of proteins into the extracellular environment is important to almost all bacteria, and in particular mediates interactions between pathogenic or symbiotic bacteria with their eukaryotic hosts. The accumulation of bacterial genome sequence data in the past few years has provided great insights into the distribution and function of these ...

Secret Sharing System and Secret Sharing Matrix
2009 International Conference on Computational Intelligence and Security, 2009To make the secret sharing management more effective and safe, based on the (k, n) threshold secret sharing scheme, this article propose a new concept of generalized (k, n)-secret sharing matrix, and proposed a more safe (t, k, n) threshold secret sharing scheme by generalizing the (t, k, n) threshold secret sharing matrix.

Keeping secret keys secret in open systems
2014 International Conference on Open Source Systems & Technologies, 2014Security of cryptographic keys stored on an untrusted host is a challenging task. Casual storage of keys could lead to an unauthorized access using physical means. If an adversary can access the binary code, the key material can be easily extracted using well-known key-finding techniques.

In this chapter, we discuss the structure, mechanism of action, and function of bacterial secretion systems as they relate to the delivery of polypeptides into the host environment. These systems encompass those that deliver proteins into the extracellular milieu where they can diffuse to nearby cells or tissues as well as those that are directly ...
