Molecular Characterisation of Cold-Adapted Metallo-Oxotransferases from the Dimethylsulfoxide Reductase Family Expressed by Antarctic Bacteria

Metadata record for data from ASAC Project 2547 See the link below for public details on this project.

Pue (greater than 90% as determined by SDS-PAGE) samples of nitrate reductase have been isolated from the Antarctic bacterium, Shewanella gelidimarina (ACAM 456T; Accession number U85907 (16S rDNA)). The protein is ~90 kDa (similar to nitrate reductase enzymes characterised from alternate bacteria) and stains positive in an in-situ nitrate reduction (native) assay technique. The protein may be N-terminal blocked, although further sequencing experiments are required to confirm this.

This work is based upon phenotyped Antarctic bacteria (S. gelidimarina; S.frigidimarina) that was collected during other ASAC projects.
