Transcriptional regulation of the plasminogen activator inhibitor type-2 (PAI-2) gene appears to be an important factor in the response of mononuclear phagocytes to inflammation. We have investigated here the molecular basis for PAI2 synthesis in monocytic cells by reporter gene deletion analysis. A DNA fragment containing 5.1 kb of 5' flanking region through to the start of the second exon was...
BACKGROUND Styrene is an important building-block petrochemical and monomer used to produce numerous plastics. Whereas styrene bioproduction by Escherichia coli was previously reported, the long-term potential of this approach will ultimately rely on the use of hosts with improved industrial phenotypes, such as the yeast Saccharomyces cerevisiae. RESULTS Classical metabolic evolution was firs...
3H-l-Phenylalanine is incorporated into a range of phenylpropanoid compounds when fed to tobacco cell cultures. A significant proportion of (3)H-trans-cinnamic acid formed from (3)H-l-phenylalanine did not equilibrate with exogenous trans-cinnamic acid and therefore may be rapidly channeled through the cinnamate 4-hydroxylase (C4H) reaction to 4-coumaric acid. Such compartmentalization of trans...
In many fungi, transcriptional responses to alkaline pH are mediated by conserved signal transduction machinery. In the homologous system in Saccharomyces cerevisiae, the zinc-finger transcription factor Rim101 is activated under alkaline conditions to regulate transcription of target genes. The activation of Rim101 is exerted through proteolytic processing of its C-terminal inhibitory domain. ...
We have isolated a cDNA for a cytochrome P450, cinnamate 4-hydroxylase (C4H), of Arabidopsis thaliana using a C4H cDNA from mung been as a hybridization probe. The deduced amino acid sequence is 84.7% identical to that of mung bean C4H and therefore was designated CYP73A5. The CYP73A5 protein was expressed in insect cells using the baculovirus expression system and when reconstituted with lipid...
