FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Dollarization and Euroization in Transition Countries: Currency Substitution, Asset Substitution, Network Externalities and Irreversibility [PDF]
We examine the extent, causes and consequences of transition countries’ use of foreign currency as a co-circulating medium of exchange and store of value.

The dynamics of inflation and currency substitution in a small open economy [PDF]
In this paper, we analyse the relationship between money and inflation in a small open economy where domestic and foreign currencies are perfect substitutes as means of payment.

Hysteresis in a simple model of currency substitution [PDF]
Journal of Monetary Economics, 1995 A simple model of currency substitution is developed in which the private cost of performing transactions in the foreign currency depends upon the aggregate degree of dollarization. This feature generates multiple steady states and hysteresis in an otherwise standard cash-in-advance model of a small open economy.

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

Prospecting the protein design landscape
FEBS Letters, EarlyView.This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Currency Substitution in the Transition Economy : A Case of the Czech Republic 1993-2001 [PDF]
Currency substitution appears to be an important issue affecting the design of monetary policy, especially in transition economies. Therefore, this paper strives to analyze the particular relevance of a currency substitution phenomenon for the Czech ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Adenosine triphosphate as a modulator of protein interactions and stability. [PDF]
FEBS Open BioATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...
