M(atrix) String Theory on K3

, 1997
We conjecture that M-theory compactified on an ALE space (or K3) is described by 0-branes moving on the ALE space. We give evidence for this by showing that if we compactify another circle, we recover string theory on the ALE space.

Inhibition of dd-Peptidases by a Specific Trifluoroketone: Crystal Structure of a Complex with the Actinomadura R39 dd-Peptidase [PDF]

Biochemistry, 2013
Inhibitors of bacterial DD-peptidases represent potential antibiotics. In the search for alternatives to β-lactams, we have investigated a series of compounds designed to generate transition state analogue structures upon reaction with DD-peptidases. The compounds contain a combination of a peptidoglycan-mimetic specificity handle and a warhead capable

Synthesis and Evaluation of 3-(Dihydroxyboryl)benzoic Acids as d,d-Carboxypeptidase R39 Inhibitors

Journal of Medicinal Chemistry, 2009
Penicillin binding proteins (PBPs) catalyze steps in the biosynthesis of bacterial cell walls and are the targets for the beta-lactam antibiotics. Non-beta-lactam based antibiotics that target PBPs are of interest because bacteria have evolved resistance to the beta-lactam antibiotics.

Interactions between non-classical β-lactam compounds and the β-lactamases of Actinomadura R39 and Streptomyces albus G [PDF]

Biochemical Journal, 1981
6-Aminopenicillanic acid, 7-aminocephalosporanic acid, mecillinam and quinacillin have varying substrate activities for both the R39 beta-lactamase (excreted by Actinomadura R39) and the G beta-lactamase (excreted by Streptomyces albus G). Cefoxitin and quinacillin sulphone are not recognized by the G beta-lactamase and are weak inactivators of the R39

A Digestive Herbal Mixture Preparation Stimulates Proton Secretion in Human Parietal Cells through Phenolic Compounds Targeting Bitter Taste Receptors

Molecular Nutrition &Food Research, Volume 70, Issue 6, 29 March 2026.
Polyphenol‐rich herbal extracts stimulate proton secretion in human parietal cells (HGT‐1) via activation of extra‐oral bitter taste receptors (TAS2Rs). A commercially available herbal mixture preparation and its nine solvent extracts show concentration‐dependent effects correlating with total polyphenol content.

Real Estate Investment Trusts’ (REITs) Asset Management Strategies Within Global REIT Portfolios

Real Estate Management and Valuation, 2021
Investment in REITs has become significant in recent years due to the stability and sustainable performance of the investment. A study on the management perspective is very important but this perspective is very limited. Asset management will derive from

Structure of the wall peptidoglycan of Streptomyces R39 and the specificity profile of its exocellular DD-carboxypeptidase-transpeptidase for peptide acceptors [PDF]

Biochemistry, 1973
Benzylpenicillin and cephaloridine reacted with the exocellular dd-carboxypeptidase–transpeptidase from Streptomyces R39 to form equimolar and inactive antibiotic–enzyme complexes. At saturation, the molar ratio of chromogenic cephalosporin 87-312 to enzyme was 1.3:1, but this discrepancy might be due to a lack of accuracy in the measurement of the ...

The Baraitser–Winter Cerebrofrontofacial Syndrome Recurrent R196H Variant in Cytoplasmic β‐Actin Impairs Its Cellular Polymerization and Stability

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
BWCFF, a severe disease with neurological symptoms, is caused by mutations in the cytoskeletal actin genes. Patient‐derived fibroblasts carrying the R196H β‐actin mutation were compared to wild type cells. The mutant cells displayed slower proliferation and migration and a lower F‐actin content, which correlated with reduced cell stiffness ...
