Reprogramming of cellular metabolism towards de novo serine production fuels the growth of cancer cells, providing essential precursors such as amino acids and nucleotides and controlling the antioxidant and methylation capacities of the cell. The enzyme serine hydroxymethyltransferase (SHMT) has a key role in this metabolic shift, and directs serine(More)
Thiamin (vitamin B1) is a pharmacological agent boosting central metabolism through the action of the coenzyme thiamin diphosphate (ThDP). However, positive effects, including improved cognition, of high thiamin doses in neurodegeneration may be observed without increased ThDP or ThDP-dependent enzymes in brain. Here, we determine protein partners and(More)
Detailed data from statistical analyses of the structural properties of the inter-domain linker peptides of the bacterial regulators of the family MocR are herein reported. MocR regulators are a recently discovered subfamily of bacterial regulators possessing an N-terminal domain, 60 residue long on average, folded as the winged-helix-turn-helix(More)
Bacterial MocR transcriptional regulators possess an N-terminal DNA-binding domain containing a conserved helix-turn-helix module and an effector-binding and/or oligomerization domain at the C-terminus, homologous to fold type-I pyridoxal 5'-phosphate (PLP) enzymes. Since a comprehensive structural analysis of the MocR regulators is still missing, a(More)
