Factorization in integral domains, II
Journal of Algebra, 1992 Les AA. continuent l'étude des propriétés des anneaux intègres, qui sont plus faibles que les propriétés de anneaux factoriels, commencé dans la première partie du papier [cf. J. Pure Appl. Algebra 69, No. 1, 1-19 (1990; Zbl 0727.13007)]. Dans cette deuxième partie sont étudiés les comportements des propriétés pour les extensions d'anneaux intègres ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding
FEBS Letters, EarlyView.In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Universally catenarian integral domains
Advances in Mathematics, 1988 The authors study (not necessarily Noetherian) integral domains R that have the property that the polynomial ring \(R[X_ 1,...,X_ n]\) is catenarian for each positive \(integer n\). Such domains are said to be universally catenarian. It is proved that a domain R with this property is a stably strong S-domain in the sense of \textit{S.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Integral Education and Fulltime Schools in Goiânia
Educação & Realidade, 2014 This article aims at identifying the school staff’s conceptions about integral education and fulltime schooling from a public school in Goiânia. It is a qualitative study based on ethnography in which the following instruments of generating data were ...

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life
FEBS Letters, EarlyView.Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Growth of HP functions in tubes
International Journal of Mathematics and Mathematical Sciences, 1981 Let C be an open convex cone in n dimensional real space Rn such that C¯ does not contain any entire straight line. We obtain a growth condition on functions in the Hardy spaces HP(TC), 1≤p≤∞, corresponding to the tube TC=Rn+iC in n dimensional complex ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
