However, some catabolic genes like amyE and XynA are regulated by carbon catabolite repression instead of substrate induction.
The biosynthesis of [alpha]-amylase in most species of the genus Bacillus is repressed by readily metabolizable substrates, especially glucose, by a mechanism of catabolite repression [22].
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.
It also is not catabolite regulated, instead environmental signals control nuclease expression.
Decrease in biomass with high xylose concentration may be due to catabolite repression during aerobic metabolism.
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).
6] exists in 7 forms: pyridoxine (PN), [1] 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.
The presence of readily metabolizable carbon sources like glucose, cellobiose, xylobiose, or xylose represses the synthesis of xylanase enzymes for the utilization of certain carbon sources such as xylan or cellulose and the process is known as catabolite repression.
A major hypoxia-responsive element was identified as a 28-base pair sequence located 900-base pairs upstream from the catabolite activator protein site of the VEGF promoter region.
The KRD1 keratinase activity decreased by the addition of carbon sources, this shows that enzyme production has catabolite repression system, support earlier study (Kainoor and Naik, 2010).
