Methionine synthase reductase (MTRR)

Involved in the reductive regeneration of cob(I)alamin (vitamin B12) cofactor required for the maintenance of methionine synthase in a functional state. Necessary for use of methylgroups from the folate cycle, thereby affecting transgenerational epigenetic inheritance.

Folate pathway donates methyl groups necessary for cellular methylation and impacts different pathways such as DNA methylation, possibly explaining the transgenerational epigenetic inheritance effects. .
