1.8.99.2 - 1.8.99.2 expressed in Eschericha coli as the N-terminal reductase domain (AcAPR1-N) and the C-terminal glutaredoxin domain (AcAPR1-C). Recombinant full-length ATP sulfurylase (AcATPS1) and recombinant full length adenosine-5'-phosphosulfate reductase (AcAPR1) from Allium cepa can form a physical association 1.8.99.2 expressed in Escherichia coli 1.8.99.2 expressed in Escherichia coli JM109 cells 1.8.99.2 expressed in Zea mays 1.8.99.2 expression in Escherichia coli 1.8.99.2 expression in Escherichia coli of a recombinant His-tagged protein and several mutants 1.8.99.2 expression in Escherichia coli of a tagged recombinant protein 1.8.99.2 full-length AprBA sequences from 20 phylogenetically distinct sulfate-reducing prokaryotes and sulfuroxidizing bacteria species are used for homology modeling. Based on the comparative models, there are no significant structural differences between dissimilatory APS reductases from sulfate-reducing prokaryotes and sulfur-oxidizing bacteria. This might be indicative for a similar catalytic process of APS reduction/sulfite oxidation 1.8.99.2 gene apsA, PCR-based DNA and amino acid sequence determination and analysis, phylogenetic analysis, expression in Escherichia coli 1.8.99.2 genes aprA and aprB, DNA and amino acid sequence determination and phylogenetic analysis, AprBA tree topology and the composition/arrangement of the apr gene loci, overview 1.8.99.2 localized expression in plastids of Arabidopsis thaliana, transgenic plants accumulate sulfite, thiosulfate, cysteine and gluthatione 1.8.99.2 overexpression in Escherichia coli 1.8.99.2 overexpression of a His-tagged recombinant protein in Escherichia coli
