Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Alkaline leaching of mechanically activated berthierite and boulangerite [PDF]

Acta Montanistica Slovaca, 2006
In this study, changes in the surface area, morphology and the leachability of antimony from mechanically activated berthierite FeSb2S4, boulangerite - Pb5Sb4S11 by a high-energy planetary mill were investigated.

Zeolit ve mermer tozu kullanılarak üretilen CAS seramiklere mekanik aktivasyonun etkisi

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018
Bu çalışmada CAS (CaO-Al2O3-SiO2)seramikleri zeolit, mermer tozu ve alümina tozları kullanılarak; 400 dev/dk ve600 dev/dk hızlarında mekanik aktivasyon ile üretilmiştir. Aktive edilen tozlarpres yardımı ile şekillendirildikten sonra 1000oC-1200oCsıcaklık

Mechanically Active Supramolecular Systems

Small Science
Mechanical sensing and transduction are integral to biological systems and have inspired research into the regulation of supramolecular self‐assembly via mechanical forces. This review presents an inaugural discussion on mechanically active supramolecular systems.

Interfacial mechanisms in active emulsions [PDF]

Soft Matter, 2014
Active emulsions,i.e., emulsions whose droplets perform self-propelled motion, are of tremendous interest for mimicking collective phenomena in biological populations such as phytoplankton and bacterial colonies, but also for experimentally studying rheology, pattern formation, and phase transitions in systems far from thermal equilibrium.

The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Focal adhesions are foci for tyrosine-based signal transduction via GIV/Girdin and G proteins. [PDF]

, 2015
GIV/Girdin is a multimodular signal transducer and a bona fide metastasis-related protein. As a guanidine exchange factor (GEF), GIV modulates signals initiated by growth factors (chemical signals) by activating the G protein Gαi.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Pleiotrophin: Activity and mechanism

, 2020
Pleiotrophin (PTN) is a potent mitogenic cytokine with a high affinity for the polysaccharide glycosaminoglycan (GAG). Although it is most strongly associated with neural development during embryogenesis and the neonatal period, its expression has also been linked to a plethora of other physiological events including cancer metastasis, angiogenesis ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...
