Activity summary

MMAB also known as methylmalonic aciduria type B protein plays a critical role in the conversion of certain molecules within the mitochondria. This protein weighing approximately 38 kDa assists in the conversion of vitamin B12 into adenosylcobalamin an active coenzyme form. MMAB is present in many tissues with significant expression in liver and kidney where significant mitochondrial activities occur. Methylmalonyl-CoA a byproduct needing processing for energy production relies on MMAB for transformation.

Biological function summary

MMAB is indispensable for vitamin B12 metabolism and mitochondrial function. This protein acts within a larger enzymatic complex that converts methylmalonyl-CoA to succinyl-CoA. By playing a role in this conversion MMAB facilitates the Krebs cycle an essential biochemical pathway for energy production. Its interaction with other proteins like methylmalonyl-CoA mutase ensures proper biochemical transformations highlighting its importance in metabolic processes.

Pathways

Methylmalonic acidemia results from disruptions in the MMAB-mediated pathway notably affecting energy metabolism. This protein integrates into the mitochondrial pathway that handles odd-chain fatty acids and amino acid breakdown. The effective collaboration of MMAB with methylmalonyl-CoA mutase ensures efficient functioning within these pathways linking MMAB to essential metabolic activities like gluconeogenesis and energy production.

Associated diseases and disorders

Mutations in MMAB contribute to methylmalonic acidemia a metabolic disorder characterized by accumulation of methylmalonic acid in the body. This condition can lead to developmental delay metabolic crisis and other severe symptoms if untreated. Alongside methylmalonyl-CoA mutase MMAB mutations impact vitamin B12-related pathways highlighting their joint role in this genetic disorder. Early diagnosis and treatment targeting this pathway help mitigate symptoms related to these enzymatic dysfunctions.
