The enzyme MTHFR is a key catalyst in the methylation cycle, a biochemical pathway that transfers methyl groups to various substrates, including DNA, proteins, and lipids. The efficiency of MTHFR in catalyzing this reaction affects the levels of homocysteine and methionine in the body. Elevated homocysteine levels are linked to various health conditions, including cardiovascular diseases, which makes the MTHFR-catalyzed reaction crucial for maintaining health.
