The C-value enigma and timing of the Cambrian explosion

open access: yes, 2008
The Cambrian explosion is a grand challenge to science today and involves multidisciplinary study. This event is generally believed as a result of genetic innovations, environmental factors and ecological interactions, even though there are many ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Biological value of raspberry fruits

open access: yesBulletin of Taras Shevchenko National University of Kyiv. Series: Problems of Physiological Functions Regulation, 2019
The human body needs a constant flow of biologically active substances. Berry products, including raspberries, are a source of natural and affordable BAS. Raspberry berries contain a complex of BAS, in particular fructose, glucose, organic acids, vitamins A, B1, B2, C, P, E, essential oils, pectins, fiber, complex of polyphenols, copper salt, iron ...

Theory of Interface: Category Theory, Directed Networks and Evolution of Biological Networks [PDF]

open access: yes, 2012
Biological networks have two modes. The first mode is static: a network is a passage on which something flows. The second mode is dynamic: a network is a pattern constructed by gluing functions of entities constituting the network.

The Value of Information for Populations in Varying Environments

open access: yes, 2010
The notion of information pervades informal descriptions of biological systems, but formal treatments face the problem of defining a quantitative measure of information rooted in a concept of fitness, which is itself an elusive notion. Here, we present a

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS 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.

THE STUDY OF BIOLOGICAL VALUE OF QUINOA SEEDS (CHENOPODIUM QUINOA WILLD.) TO CREATE SPECIALIZED FOOD PRODUCTS [PDF]

open access: yesТехника и технология пищевых производств, 2016
Nowadays, an important part of the world food problem is a shortage of protein in the diet. This is a complicated problem, the significance of which is related to the special role of protein in a human life. The negative dynamics of protein value changes
