B Weisblum,

Erythromycin inhibits protein synthesis by its effect on ribosome function (14, 118, 119). The metabolic modifications that enable cells to cope with the inhibitory action of erythromycin fall under major headings that include (i) target site alteration, (ii) antibiotic modification, and (iii) altered antibiotic transport. This minireview concentrates on target site alteration, which for erythr...

The Fic (filamentation induced by cAMP) family of proteins comprises several thousand members that are found in all domains of life [1,2]. In bacteria, these proteins are often expressed by pathogens as virulence factors that disrupt signaling in the mammalian host cell through inhibition of one or more GTPases or kinases involved in cell signaling. By integrating surprising new insights, this ...

The KING KONG parser being developed at The MITRE Corporation combines an argument-structure shorthand with recent work on the relationship between spatial and non-spatial sets of relations and a relational model of abstract relations to produce a robust approach to modifier constructions.

on analysis of tissue from rats fed GC. Despite the clearcut (P < 0.01) increase in hepatic NP-SH and GSH conseqtuent to GC feeding, there was no alteration in iodothyronine deiodination compared to the group fed glucose alone. These data indicate that the effects of diet on T4 monodeiodination in liver are not mediated by changes in the tissue level of sulfhydryl compounds but rather involve a...

In this note we settle a question posed by Hobby and McKenzie in [2] on the nature of locally finite equational classes which satisfy some nontrivial congruence identity. We settle problem #14 from [2] by exhibiting a locally finite equational class V which omits types 1 and 5 and which satisfies some non-trivial congruence identity, but which contains a finite algebra having a type 4 minimal s...

Post-translational modifications (PTMs) are chemical alterations to a protein following translation, regulating stability and function. Reversible phosphorylation is an example of an important and well studied PTM involved in a number of cellular processes. SUMOylation is another PTM known to modify a large number of proteins and plays a role in various cellular processes including: cell cycle ...

Finite element methods for which the underlying function spaces change with time are studied. The error estimates produced are all in norms that are very naturally associated with the problems. In some cases the Galerkin solution error can be seen to be quasi-optimal. K. Miller's moving finite element method is studied in one space dimension; convergence is proved for the case of smooth solutio...

The Poisson, contact and Nambu brackets define algebraic structures on C∞(M) satisfying the Jacobi identity or its generalization. The automorphism groups of these brackets are the symplectic, contact and volume preserving diffeomorphism groups. We introduce a modification of the Nambu bracket, which define an evolution equation generating the whole diffeomorphism group. The relation between th...

This squib discusses metalinguistic modification, expressives, domain modification, hypallage, and conjunctive modification within verb phrase idioms. The examples presented here show that non-combining idioms, to use terminology based on that of Nunberg, Sag & Wasow 1994, allow for modifiers on their internal constituents, but only in certain circumstances. This observation is shown to be deri...

The role of nitric oxide (NO) in cellular signaling has become one of the most rapidly growing areas in biology during the past two decades. As a gas and free radical with an unshared electron, nitric oxide participates in various biological processes. The interaction between NO and proteins may be roughly divided into two categories. In many instances, NO mediates its biological effects by act...
