FEBS Letters, EarlyView.UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

FEBS Letters, EarlyView.Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Analogies in science education: contributions and challenges [PDF]
Investigações em Ensino de Ciências, 2005 An analogy is a comparison between domains of knowledge that have similarities at the levels of characteristics and relationships. Several authors highlight the importance of this tool in the teaching and learning of difficult scientific concepts ...

Scientia et Fides, 2016 The practice of model-building is very common in analytic philosophical theology. Yet many other theologians worry that any attempt to model God must be hubristic and idolatrous.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Understanding analogical reasoning : viewpoints from psychology and related disciplines [PDF]
, 1986 Analogy and metaphor have a long history of study in linguistics, education, philosophy and psychology. Consensus over what analogy is or how analogy functions in language and thought, however, has been elusive. This paper, the first in a two part series,

Reanalysis of Passive and Negative Prefixes in Seri
Linguistic Discovery, 2002 Two productive Seri prefixes, negative and passive, are in a limited number of cases reanalyzed as part of the verb stem. This reanalysis has produced homophonous verb forms: one group is clearly analytical (affix + root) and one group is clearly ...
