The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.

The intracellular network that distributes iron-sulfur clusters in bacteria is surprisingly 'plug and play' with iron-sulfur enzymes acquired from distantly related species, whereas the intracellular electron transfer network often needs plug adapters to connect with foreign enzymes.
Structured RNA elements bind to the human methyltransferase like-3 (METTL3)-METTL14 enzyme complex with high affinity and restrict the formation of N6-deoxymethyladenosine in DNA.
Dot1l and its H3K79 methyltransferase activity are required for thermogenesis, and Dot1l is recruited by Zc3h10 to its targets genes to alter chromatin accessibility to activate the thermogenic gene program.

Antigen receptor control of methionine transport is critical to co-ordinate protein synthesis and the production of methyl donors for nucleotide and protein methylations which are required for T cell differentiation.
The coupling of the enzyme/structure core to different short linear motifs represents a novel mechanism to diversify and expand the function of signaling proteins.
