β¦ Synopsis
Superoxide dismutases (EC 1.15.1.1) are a class o f metalloproteins found in all aerobic organisms which catalyse the d i s p r o p o r t i o n a t i o n o f the superoxide anion (O 3) to H 2 0 2 and 02 providing an i m p o r t a n t defense against oxygen toxicity [1]. In the leaves o f higher plants at least two forms o f the copper-zinc enzyme are found, associated with the cytosol and the chloroplast respectively [2]. Using an a n t i b o d y raised against purified chloroplast S O D from Petunia hybrida cv. Mitchell, we screened a

The gene (sod) encoding Bacillus stearothermophilus Mn-superoxide dismutase (MnSOD) has been cloned in Escherichia coli and its entire nucleotide sequence determined. With the exception of the post-translationally cleaved N-terminal methionine residue, the predicted amino acid sequence exhibits comp
Cu-Zn superoxide dismutase (SOD-1) is a ubiquitously occurring eukaryotic enzyme with a variety of important effects on respiring organisms. A gene (dhsod-1) encoding a Cu-Zn superoxide dismutase of the marine yeast Debaryomyces hansenii was cloned using mRNA by the RT-PCR technique. The deduced ami
We have cloned DNA fragments of plasmid pFL40 fromAlcaligenesxylosoxidans ssp. denitrificans ABIV encoding a D,L-2-haloalkanoic acid halidohydrolase (DhlIV). A 6.5-kb EcoRI/SalI-fragment with inducible expression of the halidohydrolase was cloned in Pseudomonas fluorescens and Escherichia coll. A 1.
