FliI and FliJ form the FliI6FliJ ATPase complex of the bacterial flagellar export apparatus, a member of the type III secretion system. The FliI6FliJ complex is structurally similar to the α3β3γ complex of F1-ATPase. The FliH homodimer binds to FliI to connect the ATPase complex to the flagellar base, but the details are unknown. Here we report the(More)
OBJECTIVE Cardiac tamponade is a serious complication of central venous catheter (CVC) insertion. The position of the carina has been shown to be near the pericardial reflection and can easily be identified as a landmark on routine chest x-ray (CXR). The purpose of this study was to show a simple way to predict optimal CVC depth, thereby facilitating safe(More)
A soluble protein, FliJ, along with a membrane protein, FlhA, plays a role in the energy coupling mechanism for bacterial flagellar protein export. The water-soluble FliH(X)-FliI(6) ATPase ring complex allows FliJ to efficiently interact with FlhA. However, the FlhA binding site of FliJ remains unknown. Here, we carried out genetic analysis of a region(More)
The human pathogen Legionella pneumophila delivers a large array of the effector proteins into host cells using the Dot/Icm type IVB secretion system. Among the proteins composing the Dot/Icm system, an inner membrane protein DotI is known to be crucial for the secretion function but its structure and role in type IV secretion had not been elucidated. We(More)
We have various interesting time series data in our daily life, such as weather data (e.g., temperature and air pressure)and stock prices. Polyline chart is one of the most common ways to represent such time series data. We often draw multiple polylines in one space to compare the time variation of multiple values. However, it is often difficult to read the(More)
Vibrio cholerae, the etiological agent of cholera, was found to be attracted by taurine (2-aminoethanesulfonic acid), a major constituent of human bile. Mlp37, the closest homolog of the previously identified amino acid chemoreceptor Mlp24, was found to mediate taxis to taurine as well as L-serine, L-alanine, L-arginine, and other amino acids. Methylation(More)
We have various interesting time-varying data in our daily life, such as weather data (e.g., temperature and air pressure) and stock prices. Such time-varying data is often associated with other information: for example, temperatures can be associated with weather, and stock prices can be associated with social or economic incidents. Meanwhile, we often(More)
