Small heat shock proteins (sHsps) can efficiently prevent the aggregation of unfolded proteins in vitro. However, how this in vitro activity translates to function in vivo is poorly understood. We demonstrate that sHsps of Escherichia coli, IbpA and IbpB, co-operate with ClpB and the DnaK system in vitro and in vivo, forming a functional triade of chaperones. IbpA/IbpB and ClpB support independ...

Abstract In this article, we define the following: Let N 0 {{\mathbb{N}}}_{0} be set of all nonnegative integers and D = ( d i ) ∈ D={\left({d}_{i})}_...

In this paper, we give a characterization of strongly Jordan zero-product preserving maps on normed algebras as a generalization of  Jordan zero-product preserving maps. In this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly Jordan zero-product preserving maps are completely different. Also, we prove that the direct p...

We prove that pillage games [Jordan, 2006, “Pillage and property”, JET] can have multiple stable sets, constructing pillage games with up to 2 n−1 3 stable sets, when the number of agents, n, exceeds four. We do so by violating the anonymity axiom common to the existing literature, instead endowing some agents to overpower all but a small number of opposing configurations of agents. Thus, when ...

A general expression for the π − N and π − ∆ scattering lengths is derived in the framework of a microscopic calculation. Annihilation, negative energy wavefunctions and spontaneous chiral symmetry are included consistently. The point-like limit is used to calculate the scattering lengths.

Yeast cells almost completely deficient in all cytochromes were obtained by introducing two defective nuclear genes, cyd1 and cyc4, into the same haploid strain. The action of the two mutant genes is synergistic, since either gene acting singly results in only partial cytochrome deficiency. Normal synthesis of all cytochromes can be restored in the double mutant by adding delta-aminolevulinic a...
