Enzymes play a key role in cellular metabolic processes. To enable the quantitative assessment of these processes, researchers need to know the so-called 'turnover number' (for short: kcat) of the enzymes. A team of bioinformaticians now describes a tool for predicting this parameter for various enzymes using AI methods.

Wormlike animals are first amphibians shown to pass microbes to their offspring
Caecilians are an illusive type of snakelike amphibian that live in aquatic and subterranean environments. In some species, mothers produce a special type of nutrient-rich skin that juveniles consume, similar to the way in which humans breastfeed their children. A new study shows this behavior passes on microbes to juvenile...
How Do Microbes Spread Globally? A Study Clarifies How They Travel From End to End of the World
CEAB-CSIC researchers have published a scientific article that helps to understand the intercontinental dispersion of harmful microorganisms through the atmosphere.
Colorado River Basin Has Lost Water Equal to Lake Mead Due to Climate Change
From 2000 to 2021, climate change caused the loss of more than 40 trillion liters (10 trillion gallons) of water in the Colorado River Basin — about equal to the entire storage capacity of Lake Mead — according to a new study that modeled humans’ impact on hydrology in the...
Crews Head Down River, Out to Sea to Prep New SWOT Water Satellite
A lot of hard work goes into ensuring a spacecraft like the Surface Water and Ocean Topography satellite delivers accurate data.
Advancing chemical recycling of waste plastics
New research focuses on optimizing a promising technology called pyrolysis, which can chemically recycle waste plastics into more valuable chemicals.
Study improves understanding of how bacteria benefit plant growth
Scientists have found that competition between strains of beneficial bacteria in the soil degrades the service that the bacteria provide to their hosts.
Unlocking Secrets of the Elusive Ghost Shark
Researchers from the University of Florida and the Seattle Aquarium are exploring 100 meters underwater in the Pacific Northwest this summer to learn more about mysterious ghost sharks, one of the strangest beasts from the depths of the ocean.
Risk of Fatal Heart Attack May Double in Heat Wave & High Fine Particulate Pollution Days
The combination of soaring heat and smothering fine particulate pollution may double the risk of heart attack death, according to a new study of more than 202,000 heart attack deaths in China.
Revealing HIV drug-resistance mechanisms through protein structures
Researchers have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV. Their findings reveal how changes to the 3D structures of integrase, an HIV protein, can lead to Dolutegravir resistance and how...
