An Arctic marine bacterial strain collection was established consisting of 1448 individual ... -
Manganese acquisition is facilitated by PilA in the cyanobacterium Synechocystis sp. PCC 6803
Hohmann-Marriott, Martin Frank; Lamb, Jacob Joseph (Journal article; Peer reviewed, 2017)Manganese is an essential element required by cyanobacteria, as it is an essential part of the oxygen-evolving center of photosystem II. In the presence of atmospheric oxygen, manganese is present as manganese oxides, which ... -
mCherry contains a fluorescent protein isoform that interferes with its reporter function
Fages-Lartaud, Maxime René; Tietze, Lisa; Elie, Florence; Lale, Rahmi; Hohmann-Marriott, Martin Frank (Peer reviewed; Journal article, 2022)Fluorescent proteins are essential reporters in cell and molecular biology. Here, we found that red-fluorescent proteins possess an alternative translation initiation site that produces a short functional protein isoform ... -
NMR-Structural Analysis of Proteins from Oil Reservoir Metagenomes
Erlandsen, Hilde Opdahl (Master thesis, 2015)Microorganisms are found ubiquitously around the world, where they survive as a result of their specialized biochemical reactions and enzymes. In the extreme environment of deep sea oil reservoirs, the microbes have to ... -
Oil degrading potentials of cold-loving (psychrophilic) bacteria
Cimmino, Lorenzo (Master thesis, 2015)A collection of 1400 psychrophilic isolates, belonging to 31 different genera, has been screened with the intent to identify the strains that harbor the ability to degrade polycyclic aromatic hydrocarbons (PAHs). The 16S ... -
Overview of tRNA Modifications in Chloroplasts
Fages-Lartaud, Maxime René; Hohmann-Marriott, Martin Frank (Peer reviewed; Journal article, 2022)The chloroplast is a promising platform for biotechnological innovation due to its compact translation machinery.
