Activity summary

DLST also known as dihydrolipoamide S-succinyltransferase is an essential component of the 2-oxoglutarate dehydrogenase complex (OGDC). It possesses a molecular mass of approximately 48 kDa. Expressed primarily in mitochondrial matrices within mammalian tissues DLST plays a mechanical role in catalyzing the transfer of succinyl groups to coenzyme-A from S-succinyldihydrolipoyllysine. The target is integral to the energy metabolism processes occurring within cells especially in tissues with high energy demands such as the heart and skeletal muscles.

Biological function summary

The DLST enzyme acts within the tricarboxylic acid (TCA) cycle also known as the Krebs cycle or citric acid cycle. It forms a critical part of the multi-enzyme complex OGDC facilitating the oxidative decarboxylation of 2-oxoglutarate an important step in the TCA cycle. Through this action DLST helps produce succinyl-CoA a molecule pivotal for energy and biosynthetic processes. The activity of this protein ensures continuous energy supply and intermediary metabolite flow within cellular respiration.

Pathways

DLST plays a significant role within both the TCA cycle and the broader metabolic pathway of oxidative phosphorylation. These are important for efficient cellular energy production connecting many metabolic reactions and facilitating ATP generation. OGDC where DLST performs its function interacts with various proteins such as E1 (2-oxoglutarate dehydrogenase) and E3 (dihydrolipoamide dehydrogenase). This interaction is necessary to efficiently process and interconvert energy substrates for cellular use.

Associated diseases and disorders

DLST has been implicated in conditions such as neurodegenerative diseases including Alzheimer's disease. Alterations in DLST activity or expression can lead to energy production defects contributing to the metabolic disturbances observed in these conditions. Additionally mutations or dysregulation within the OGDC complex featuring DLST are associated with some forms of cancer where metabolic reprogramming occurs. In both contexts the interaction between DLST and other complex components such as E3 displays potential involvement in disease mechanisms marking it as a target worth studying for therapeutic interventions.
