Structural and functional characterization of a cold-adapted stand-alone TPM domain reveals a relationship between dynamics and phosphatase activity [PDF]
The TPM domain constitutes a family of recently characterized protein domains that are present in most living organisms. Although some progress has been made in understanding the cellular role of TPM-containing proteins, the relationship between ...

Discovering structural motifs using a structural alphabet: Application to magnesium-binding sites [PDF]
BACKGROUND: For many metalloproteins, sequence motifs characteristic of metal-binding sites have not been found or are so short that they would not be expected to be metal-specific.

Rates of Spontaneous Cleavage of Glucose, Fructose, Sucrose, and Trehalose in Water, and the Catalytic Proficiencies of Invertase and Trehalas [PDF]
Most of the early experimental work on enzyme kinetics was based on the properties of yeast invertase (-fructo-furanosidase, EC 3.2.1.26), whose robust activity1 (together with the availability of a continuous polarimetric assay) enabled Michaelis and ...

Deep electromagnetic stimulation (DEMS) and low‐frequency ultrasound (US) are new physical therapy methods used in the rehabilitation of the musculoskeletal system and wound healing. They are applied locally to treat the injured tissues. The beneficial effects of these methods in supportive care have been documented, but accurate biochemical effects ...

Phosphatases in the soil environment [PDF]
Enzymes play a key role in nutrient cycling in the soil environment. In this work, four phosphatases of the soil environment were investigated. A study of the effect of metal ions and metal ion concentrations on inorganic pyrophosphatase activity in ...

Micellar electrokinetic chromatography after precapillary enzyme assay for the determination of phosphatase activity in semiarid soil [PDF]
Inorganic phosphorous (P) is an essential plant nutrient that must be added to most soils to maintain plant growth and sustain crop yields. Phosphatase enzymes play a major role in the processes of mineralization of organic P substrates.

Link between allosteric signal transduction and functional dynamics in a multi-subunit enzyme: S-adenosylhomocysteine hydrolase [PDF]
S-adenosylhomocysteine hydrolase (SAHH), a cellular enzyme that plays a key role in methylation reactions including those required for maturation of viral mRNA, is an important drug target in the discovery of antiviral agents. While targeting the active site is a straightforward strategy of enzyme inhibition, evidences of allosteric modulation of ...
