Green fluorescent protein (GFP) is a bioluminescent polypeptide isolated from the jellyfish Aequorea victoria. GFP converts the blue chemiluminescence of aequorin into green fluorescent light. In the laboratory, GFP can be incorporated into a variety of biological systems in order to function as a marker protein. Since its discovery in 1962, GFP has become a significant contributor to the research of monitoring gene expression, localization, mobility, traffic, or interactions between various membrane and cytoplasmic proteins.

A periplasmic flagellar chaperone protein, FlgA, is required for P-ring assembly in bacterial flagella of taxa such as Salmonella enterica or Escherichia coli. Here we present the open and closed crystal structures of FlgA from Salmonella enterica serovar Typhimurium, grown under different crystallization conditions. An intramolecular disulfide cross-linked form of FlgA caused a dominant negative effect on motility of the wild-type strain.

This tutorial is designed for high school and beginning college students. When we breathe oxygen from the air is taken up by blood in our lungs and soon delivered to each of the cells in our body through our circulatory system. Among other uses, our cells use oxygen as the final electron acceptor in a process called aerobic respiration – a process that converts the energy in food and nutrients into a form of energy that the cell can readily use (molecules of ATP, adenosine triphosphate).
