In this study, we demonstrated that mcl-PHA biosynthesis on xylose does not occur when xylA and xylB are expressed even under nitrogen limitation, perhaps because the expression of xylAB channels the metabolic flux to central metabolism such as TCA cycle for cell maintenance or/and to production of side products like acetate, rather than to PHA synthesis.
Thus, in RCC4-EV cells, HIF-1α and HIF-2α proteins are expressed even under 20% oxygen concentrations20.
For instance, the A. oryzae homologs of the aflatoxin biosynthesis gene cluster are not expressed even under conditions that are favorable for aflatoxin production in A. flavus and Aspergillus parasiticus (Kusumoto et al. 1998; Watson et al. 1999; Takahashi et al. 2002; Zhang et al. 2005).
However, in the lung, RAGE is highly expressed even under normal physiological conditions, and it is believed to have a homeostatic function [ 2].
The other beta type CA (45443) is probably located in the ER or the periplasmic space and is constitutively expressed even under high CO2 concentrations [42].
Consistent with a previous report20, HIF-1α and HIF-2α proteins were constitutively expressed even under 20% O2 conditions in RCC4-EV cells at comparable levels to those of RCC4-VHL cells under 1% O2 conditions.
Moreover, the possibility that different ST genes might be expressed in different growth conditions, even under different biotic interactions, cannot not be ruled out.
Without the words, the idea cannot even be expressed.
In contrast, HSPA1 can be expressed in interstitial somatic cells but not in meiotic cells, even under heat shock (Huang et al. 2001).
Thus, under this condition can be expressed as (13).
