Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS 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 ...

Determinantes de los precios reales de las materias primas agrícolas. El papel de los inventarios y de los factores macroeconómicos (1960-2010)

open access: yesLecturas de Economía, 2012
In recent years, there has been an extraordinary increase in international commodity prices, such as fossil fuels (oil) and agricultural products. This paper analyzes the behavior of real prices of major agricultural commodities (wheat, corn, soybeans ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS 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 ...

Recent progress in greenhouse gas inventory improvement for cattle emissions in Africa highlights priorities for further research

open access: yesFrontiers in Animal Science
We analysed national Tier 2 greenhouse gas (GHG) inventories for dairy and other cattle in ten East and Southern Africa (ESA) countries to evaluate the variation and predictors of enteric methane (CH4) emission factors (eEFs), and highlight priorities ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Inventories, Markups, and Real Rigidities in Menu Cost Models [PDF]

open access: yes
Real rigidities that limit the responsiveness of real marginal cost to output are a key ingredient of sticky price models necessary to account for the dynamics of output and inflation.

On the relationship between effective demand and income distribution in a Kaleckian framework

open access: yesPSL Quarterly Review, 2014
The work takes up some issues raised by Kalecki in his posthumously published article “Class struggle and distribution of national income”. By using Marx’s schemes of reproduction, Kalecki was able to prove that, in a given short period, a part of the ...

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Is Eighty Percent of Success Just Showing Up? Student Compliance and Refusal to Complete an Advisement Form as an Indicator of First-Term GPA

open access: yesJournal of College Orientation, Transition, and Retention, 2009
Motivation and, inferentially, commitment are critical, non-cognitive factors in college success. One needs to detect and measure these attributes prior to a student's acutal enrollment in classes since early detection of at-risk students can lead to the

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
