The biochemical function of LEUCINE CARBOXYL METHYLTRANSFERASE 1 (LCMT1) is to transfer a methyl group from the methyl donor S-adenosylmethionine (SAM) to the catalytic subunits of PROTEIN PHOSPHATASE 2A (PP2Ac), PP4 and PP6. This post-translational modification by LCMT1 is found throughout eukaryotes from yeast to animals and plants, indicating that its function is essential. However, Arabidopsis with knocked out LCMT1 still grows and develops almost normally, at least under optimal growth conditions.

- Considerable amounts of persistent organic pollutants (POPs) in the Arctic cryosphere are influenced by climate change, affecting their occurrence in marine systems.
- The study focused on how land-derived pollutants, specifically polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB), interact with Arctic coastal waters by sampling riverine suspended particulate matter (SPM) and marine sediments.
- Findings indicated that while freshwater and terrestrial inputs generally raise concerns about contaminant levels, in Svalbard, these inputs may dilute contaminant concentrations in nearshore sediments, potentially altering the bioavailability of POPs in the marine food web.
