FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Sympathy, cumulativity, and the Duke-of-York gambit [PDF]
, 2003 The Duke-of-York gambit (Pullum 1976) involves derivations of the form A->B->A, where underlying /A/ passes through an intermediate stage B before returning to A at the surface.

PARETO-OPTIMALITY AND L-OPTIMAL FOR SOLVING SOME CLASSES OF OPTIMAL CONTROL PROBLEM
Финансы: теория и практика, 2017 Many practical problems of economic activities and a number of important issues of economic theory are connected to the choice of optimal solution. An adequate economic theory should reflect the process of continuous development of the economic system ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Non-computable functions in Optimality Theory
, 1999 Is Optimality Theory a constraining theory? A formal analysis shows that it is, if two auxiliary assumptions are made: (1) that only markedness and faithfulness constraints are allowed, and (2) that input and output representations are made from the same

Features in Optimality Theory: A Computational Model
, 1999 This dissertation presents a computational model of Optimality Theory (OT) (Prince and Smolensky 1993). The model provides an efficient solution to the problem of candidate generation and evaluation, and is demonstrated for the realm of phonological ...

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 ...

Parallelism and Planes in Optimality Theory: Evidence from Afar
, 1997 In this dissertation I show that the representations in Optimality Theory must be extended to allow multiple planes. The variable-position affixes in Afar occur as either prefixes or suffixes depending on the initial segment of the verb root. If the root
