Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

A cross-linguistic study of lexical and derived antonymy
LinguisticsAntonymy is the lexical relation of opposition. The nature of the oppositeness may differ – e.g., contradictory (‘true’–‘false’) or gradable (‘tall’–‘short’) – and there may be variation as to the relationship in their formal encoding, whether the ...

SYNONYMS AND ANTONYMS EXPRESSING THE CONCEPT OF "MAN" [PDF]
Vestnik Issyk-Kulʹskogo universitetaPedagogy, psychology, philosophy, sociology, ethnography, etc. is well known that although the topic of man has been studied in science, synonyms and antonyms, which are linguistic means associated with man, have not been specifically studied as an ...

Synonyms, Antonyms and Retroactive Inhibition with Meaningful Material
, 1973 In the paired-associate literature negative transfer paradigms, e.g., (A—B, A—C), impede List 1 recall. Positive transfer paradigms, e.g., (A—B, A—B synonym), do not contribute to List 1 forgetting.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
FEBS Open Bio, EarlyView.Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

A distributional study of negated adjectives and antonyms [PDF]
, 2018 In this paper, we investigate the relation between negated adjectives and antonyms in English using Distributional Semantics methods. Results show that, on the basis of contexts of use, a negated adjective (e.g., not cold) is typically more similar to ...
