These results appear to support catabolite
repression by glucose and sorbitol with prodigiosin production.
Irene Weber continued her structural investigation of the Escherichia coli catabolite
gene activator protein (CAP).
To determine why the reb D gene was not being expressed, sequence analysis upstream of the open reading frame was perforrned, and a potential catabolite
repressor sequence was identified.
The decreased activity in the later phase of growth was probably due to catabolite
repression by glucose released from starch hydrolysis.
Relaxation of catabolite
repression in streptomycin-dependent Escherichia coli.
Since the high dosage of the additional carbon sources like glucose and fructose lead to catabolite
repression, here pectin in the orange peel as the carbon source along with the organic nitrogen source improved the pectinase production.
We tested for assay interference in the presence of the folate catabolite
apABG (32) and the antifolate drug methotrexate, both of which have a p-aminobenzoylglutamyl moiety (33).
Decrease in biomass with high xylose concentration may be due to catabolite
repression during aerobic metabolism.
6] exists in 7 forms: pyridoxine (PN),  pyridoxine 5'-phosphate (PNP), pyridoxal (PL), pyridoxal 5'-phosphate (PLP), pyridoxamine (PM), pyridoxamine 5'-phosphate (PMP), and the catabolite
, 4-pyridoxic acid (PA; Fig.
Our results indicate that there is an overproduction of hydrogen sulfide in Down syndrome, thiosulfate being the main catabolite
of hydrogen sulfide.
Supplemental fructooligosaccharides and mannanoligosaccharides influence immune function, ileal and total tract nutrient digestibilities, microbial populations and concentrations of protein catabolites
in the large bowel of dogs.
from microbiota engage aryl hydrocarbon receptor and balance mucosal reactivity via interleukin-22.
