Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

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 ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

In Vitro Rumen Degradability of Phenolic Compound and Antioxidant Activity of Moringa oleifera Leaf

Jurnal Peternakan Indonesia, 2017
The research was aimed to study the degradability of phenolic compounds and antioxidant activity of moringa leaves (Moringa oleifera) in the rumen in vitro. Moringa and Leucaena (Leucaena leucocephala, as a comparison) leaves were incubated in goat rumen

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

In Vitro Degradation of Oxalic Acid by Human Feces [PDF]

International Journal of Urology, 1996
Background: Oxalic acid‐degrading bacteria have been isolated from human feces. Therefore, the possibility exists that oxalic acid in food is degraded in human intestine by such bacteria, and absorption and excretion of oxalic acid is reduced. It may be possible that patients who form idiopathic stones have fewer oxalic acid‐degrading bacteria than ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Turmeric rhizomes reduced in vitro methane production and improved gas production and nutrient degradability

Animal Biotechnology
The present study aimed to evaluate the effect of dry turmeric rhizomes on in vitro biogas production and diet fermentability. Turmeric rhizomes were included at gradually increased levels: 0, 0.5, 1, 1.5 and 2% of a diet containing per kg dr matter (DM):

DNA ligase LigE increases bacterial transformation with damaged extracellular DNA

FEBS Letters, EarlyView.
The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

EFEITO DE ENZIMAS FIBROLÍTICAS SOBRE A DEGRADAÇÃO MICROBIANA RUMINAL DA FIBRA DE CANA-DE-AÇÚCAR

Ciência Animal Brasileira, 2010
Aiming to study the limiting factors for degradation of sugarcane fiber to be used as cattle feed, sugarcane fibrous components were fractioned in neutral- and acid-detergent fibers (respectively, NDF and ADF).
