The npd gene cluster, which encodes the enzymes of a p-nitrophenol catabolic pathway from Arthrobacter sp. strain JS443, was cloned and sequenced. Three genes, npdB, npdA1, and npdA2, were independently expressed in Escherichia coli in order to confirm the identities of their gene products. NpdA2 is a p-nitrophenol monooxygenase belonging to the two-component flavin-diffusible monooxygenase fam...
The role of the oxygen of the benzopyran substituent of Delta(9)-tetrahydrocannabinol in defining affinity for brain cannabinoid (CB(1)) receptors is not well understood; however, it is known that opening the pyran ring can result in either increased potency and affinity, as in CP 55,940 [(-)-cis-3-[2-hydroxy-4(1,1- dimethyl-heptyl)phenyl]-trans-4-(3-hydroxy-propyl)cyclohexanol], or in an inact...
The oily droplets exuded from the root hairs of sorghum are composed of a 1:1 ratio of sorgoleone and its lipid resorcinol analogue. The production of these droplets appears to be suppressed when c. 20 microg of exudate mg(-1) root dry weight accumulates at the tip of the root hairs. However, more exudate is produced following gentle washing of the roots with water, suggesting that the biosynth...
