Substrate preferences in rumen bacteria: evidence of catabolite regulatory mechanisms.

The type of linker plays an important role in ADC catabolite products with regard to processing into targeted cells or metabolizing by clearance mechanisms.

aureus accessory gene regulator operon (agr) via the effector molecule RNAIII (10), the staphylococcal respiratory response regulator AB (SrrAB) (10), a glucose catabolite repressor CcpA (11), the staphylococcal accessory regulator A, [[sigma].sup.B] (12) and the SaeRS 2-component system (13).

Moreover, high ML levels paralleled high intensity of GPC catabolite signal (Figure 3(i)).

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.

[alpha]-Amylase production from catabolite derepressed Bacillus subtilis KCC103 utilizing sugarcane bagasse hydrolysate.

Glucose is preferentially metabolized via anaerobic glycolysis to form nonfermentable carbon compounds, particularly ethanol, and it exerts a strong catabolite repression with either enzymes required for respiration or enzymes of the Krebs cycle [11, 32].

Catabolite repression on enzymes production apparently occurred at the hour of maximum enzyme production, which resulted in lowering of the reducing sugar levels.
