Publisher Summary L-Rhamnose isomerase is an enzyme inducible in a great variety of microorganisms by growing them in the presence of L-rhamnose. The method described uses Lactobacillus plantarum as the source of the enzyme. The assay procedure is based on the appearance of the 2-keto sugar L-rhamnulose, which is measured by the cysteine–carbazole ...

Synthesis of a first-generation l-rhamnose dendron
Tetrahedron Letters, 2020Abstract During the last few years, various strategies for cancer therapy have emerged where l -rhamnose interacts with either an anti-rhamnose antibody or a hypothetically over-expressed l -rhamnose-binding lectin. These studies have led to promising results in cancer immunotherapy and the design of selective cytotoxic rhamnosides, respectively ...

Alternate pathways of l-rhamnose transport in Arthrobacter pyridinolis
Archives of Biochemistry and Biophysics, 1974Abstract Phosphoenolpyruvate: hexose phosphotransferase-negative mutants of Arthrobacterpyridinolis fail to grow on l -rhamnose. Although phosphoenolpyruvate: l -rhamnose phosphotransferase activity could not be consistently demonstrated in extracts of rhamnose-grown cells, low levels of phosphoenolpyruvate-dependent uptake of rhamnose were found

Insulinotropic action of L-rhamnose in isolated rat islets
Acta Diabetologica Latina, 1981L-Rhamnose at different concentrations stimulated incorporation of 3H-leucine both into islet (pro)insulin and that released into the medium. Maximum isotope incorporation with either glucose or rhamnose was seen at a concentration of 16.7 mM, although the glucose-induced effect was significantly greater.

The enzymic synthesis of uridine diphosphate L-rhamnose
Biochemical and Biophysical Research Communications, 1962Abstract It has been reported that an enzyme preparation from mung bean leaves (Phaseolus aureus) catalyzes the transfer of L-rhamnose from thymidine diphosphate (dTDP) L-rhamnose to 3-quercetin β-D-glucoside to form rutin (3-quercetin O-α-L-rhamnosyl-(1 → 6)-β-D-glucoside) ( Barber and Neufeld, 1961 ; Barber, 1962 ).

Cloning and characterization of the l-rhamnose regulon in Salmonella typhimurium LT2
Gene, 1991A Salmonella typhimurium LT2 cosmid library was constructed, and a 46-kb recombinant plasmid was isolated that could complement an Escherichia coli rha mutant. Subsequent subcloning generated a 13.6-kb ClaI restriction fragment that contained a functional regulatory element.

The variation of dTDP-l-rhamnose pathway genes in Vibrio cholerae
Microbiology, 2003The genetic variation in the dTDP-l-rhamnose pathway genes (rmlA, rmlB, rmlC and rmlD) in Vibrio cholerae was investigated. The genes are part of the O antigen gene cluster and the aim was to study lateral gene transfer of O antigen gene clusters. The rml genes of an O6 strain were cloned using an Escherichia coli K-12 strain designed for selecting ...

Synthesis of uridine diphosphate l-rhamnose by enzymes of Chlorella pyrenoidosa
Archives of Biochemistry and Biophysics, 1967Abstract An enzyme system obtained from light-grown cultures of the green alga, Chlorella pyrenoidosa, is shown to catalyze the reduction and epimerization of uridine diphosphate d -glucose to a compound characterized as uridiue diphosphate l -rhamnose; TPNH is required in the reaction. Uridine diphosphate d -galactose and thymidine diphosphate d
