Bacterial Signal Peptides- Navigating the Journey of Proteins
Frontiers in Physiology, 2022 In 1971, Blobel proposed the first statement of the Signal Hypothesis which suggested that proteins have amino-terminal sequences that dictate their export and localization in the cell.

The ESX-1 Substrate PPE68 Has a Key Function in ESX-1-Mediated Secretion in Mycobacterium marinum
mBio, 2022 Mycobacteria use specialized type VII secretion systems (T7SSs) to secrete proteins across their diderm cell envelope. One of the T7SS subtypes, named ESX-1, is a major virulence determinant in pathogenic species such as Mycobacterium tuberculosis and ...

TooT-T: discrimination of transport proteins from non-transport proteins [PDF]
BMC Bioinformatics, 2020 Abstract Background Membrane transport proteins (transporters) play an essential role in every living cell by transporting hydrophilic molecules across the hydrophobic membranes. While the sequences of many membrane proteins are known, their structure and function is still not well characterized and understood, owing to the immense effort needed to ...

Nucleoside Transporter Proteins
Current Vascular Pharmacology, 2009 Concentrative nucleoside transporters (CNT; SLC28) and equilibrative nucleoside transporters (ENT; SLC29) mediate the uptake of natural nucleosides and a variety of nucleoside-derived drugs, mostly used in anticancer therapy. SLC28 and SLC29 families consist in three and four members, respectively, which differ in their substrate selectivity and their ...

Thermal stability of solitons in protein $α$-helices [PDF]
Chaos, Solitons and Fractals 2022; 155: 111644, 2022 Protein$\alpha$-helices provide an ordered biological environment that is conducive to soliton-assisted energy transport. The nonlinear interaction between amide I excitons and phonon deformations induced in the hydrogen-bonded lattice of peptide groups leads to self-trapping of the amide I energy, thereby creating a localized quasiparticle (soliton ...

The Role of Light–Dark Regulation of the Chloroplast ATP Synthase
Frontiers in Plant Science, 2017 The chloroplast ATP synthase catalyzes the light-driven synthesis of ATP and is activated in the light and inactivated in the dark by redox-modulation through the thioredoxin system.

Inositol transport proteins [PDF]
FEBS Letters, 2015 The cyclic polyol myo‐inositol is a key molecule in many different metabolic pathways among all organisms; in addition, it is fundamental for osmotic balance in the mammalian brain. This review sums up inositol transporters from eukaryotic organisms, elucidating their vital role in regulating the intracellular distribution and uptake of inositol.
