Interestingly, [C.sub.16]-[C.sub.23] aryl isoprenoids were detected from extracts from solid bitumen from wells HB101, LG82, and YB101 in the western gas fields (Figure 5).
What is more, n-alkanes and isoprenoid hydrocarbon in the crude oil and Chang 7 source rocks are similarly distributed, whose carbon number distribution ranges broadly with one single peak; the terpenoid and steroid are similar obviously, the content of tetracycline is high, the homohopanes with high carbon number appears in pairs, the content of tricyclene is low, and the content of regular Steranes [C.sub.29] is higher than [C.sub.27] in steroid.
Deinococcus bacteria are naturally equipped with capabilities that make them conducive to such development: natural expression of carotenoids (key subfamily of the isoprenoid pathway), assimilation of various carbon sources, and adaptation to high-flow metabolic engineering

(1997) cloned an HMGS gene induced by ozone in Pinus sylvestris, and showed that ozone might regulate isoprenoid biosynthesis by upregulating PsHMGS expression.
We suggest that HMGCR inhibition would be one of the multiple effects that isoprenoid compounds seem to be exerting on the MP, though that possibility had not yet been specifically elucidated previously.
Ubiquinone, also known as CoQ, is an isoprenoid component and lipid-soluble molecule which plays various roles in both eukaryotic and prokaryotic cells.

In malaria, the investigational drug, fosmidomycin, blocks isoprenoid synthesis, killing the parasite, but, over time the drug often becomes less effective.

Studies in plants have emphasized the importance of compartmentalization in the control of terpene biosynthesis [160], challenging the traditional view of isoprenoid metabolism occurring in a homogeneous environment with intermediates mixing freely and accessible to successive or competing enzymes.
