Seed and Foliar Application of Amino Acids Improve Variables of Nitrogen Metabolism and Productivity in Soybean Crop

open access: yesFrontiers in Plant Science, 2018
The application of amino acids in crops has been a common practice in recent years, although most of the time they are associated with products based on algae extracts or on fermented animal or vegetable wastes.

Cysteine homeostasis.

open access: yes, 2015
of essential biomolecules, such as vitamins, cofactors, antioxidants and many defence compounds, that are formed in response to adverse environmental conditions in which the sulfur moiety is the functional group. Sulfate is transported inside the plant, reduced to sulfide and incorporated into O-acetylserine (OAS) to form cysteine.

Cysteine proteases in atherosclerosis

open access: yesThe FEBS Journal, 2017
Atherosclerosis predisposes patients to cardiovascular diseases, such as myocardial infarction and stroke. Instigation of vascular injury is triggered by retention of lipids and inflammatory cells in the vascular endothelium. Whereas these vascular lesions develop in young adults and are mostly considered harmless, over time persistent inflammatory and

Characterization of Trypanosoma brucei gambiense variant surface glycoprotein LiTat 1.5 [PDF]

open access: yes, 2012
At present, all available diagnostic antibody detection tests for Trypanosoma brucei gambiense human African trypanosomiasis are based on predominant variant surface glycoproteins (VSGs), such as VSG LiTat 1.5. During investigations aiming at replacement

Protease inhibitors targeting coronavirus and filovirus entry. [PDF]

open access: yes, 2015
In order to gain entry into cells, diverse viruses, including Ebola virus, SARS-coronavirus and the emerging MERS-coronavirus, depend on activation of their envelope glycoproteins by host cell proteases.

Estimation of bacterial hydrogen sulfide production in vitro

open access: yesJournal of Oral Microbiology, 2015
Oral bacterial hydrogen sulfide (H2S) production was estimated comparing two different colorimetric methods in microtiter plate format. High H2S production was seen for Fusobacterium spp., Treponema denticola, and Prevotella tannerae, associated with ...

Autophagy is activated and involved in cell death with participation of cathepsins during stress-induced microspore embryogenesis in barley [PDF]

open access: yes, 2018
Microspores are reprogrammed towards embryogenesis by stress. Many microspores die after this stress, limiting the efficiency of microspore embryogenesis. Autophagy is a degradation pathway that plays critical roles in stress response and cell death.

The intracellular domain of TLR2 is capable of high‐affinity Zn binding: possible outcomes for the receptor activation

open access: yesFEBS Letters, EarlyView.
Toll‐like receptors (TLRs) are important in the innate immune system. This study explores the zinc‐binding ability of the TLR2 TIR domain (TLR2TIR). We found that TLR2TIR binds zinc with nanomolar affinity through its cysteine residues. Two of them, C673 and C713, are vital for receptor activation, indicating that zinc may play a role in initiating ...

The effects of nitroxyl (HNO) on soluble guanylate cyclase activity: interactions at ferrous heme and cysteine thiols [PDF]

open access: yes, 2009
It has been previously proposed that nitric oxide (NO) is the only biologically relevant nitrogen oxide capable of activating the enzyme soluble guanylate cyclase (sGC). However, recent reports implicate HNO as another possible activator of sGC.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...
