STUDIES ON BACTERIAL LOAD OF FISH CONTAINER-II
NIPPON SUISAN GAKKAISHI, 1963 In the previous paper1), the author reported on the invasion of the Takikawa's so-called pathogenic halophilic bacteria into the material of wooden fish container. It was also disclosed that the bacteria might easily migrate into inner part of such rough-grained wooden material as ceder or pine.

Switching of the Bacterial Flagellar Motor Near Zero Load [PDF]
Journal of Molecular Biology, 2009 Flagellated bacteria, such as Escherichia coli, are able to swim up gradients of chemical attractants by modulating the direction of rotation of their flagellar motors, which spin alternately clockwise (CW) and counterclockwise (CCW). Chemotactic behavior has been studied under a variety of conditions, mostly at high loads (at large motor torques ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

ABLE: An Automated Bacterial Load Estimator for the Urinoculture Screening
Proceedings of the 5th International Conference on Pattern Recognition Applications and Methods, 2016 Urinary Tract Infections (UTIs) are very common in women, babies and the elderly. The most frequent cause is a bacterium, called Escherichia Coli, which usually lives in the digestive system and in the bowel. Infections can target the urethra, bladder or kidneys.

Autonomous Generation and Loading of DNA Guides by Bacterial Argonaute [PDF]
Molecular Cell, 2017 Several prokaryotic Argonaute proteins (pAgos) utilize small DNA guides to mediate host defense by targeting invading DNA complementary to the DNA guide. It is unknown how these DNA guides are being generated and loaded onto pAgo. Here, we demonstrate that guide-free Argonaute from Thermus thermophilus (TtAgo) can degrade double-stranded DNA (dsDNA ...
