Function
AASS is an enzyme involved in amino acid metabolism. It catalyzes the transformation of glutamate semialdehyde into aminoadipate semialdehyde via a two-step reaction. The first step involves hydroxylation of the α-carbon atom of glutamate semialdehyde, which can be followed by either hydrolysis or dehydration depending on whether water is present or not. In the second step, NADPH is added to form aminoadipate semialdehyde and NADP+. This molecule serves as an important intermediate for several biosynthetic pathways involving metabolites such as lanosterol and cholesterol esters. As such, it's important for controlling the flow of chemicals through these pathways and maintaining appropriate levels within an organism's body.
Role in Biosynthesis
Aminoadipate Semialdehyde Synthase (AASS) plays a vital role in the synthesis of various compounds within cells that are crucial for bodily functions. These molecules include sterols like lanosterol and cholesterol esters for example lathosterol, which are fundamental components for maintaining membrane structures such as cell walls. AASS also participates in many other biosynthetic pathways as it helps to channel molecules into other metabolic sequences where they can be further processed into their final products and used by cells throughout the body.
Essential Questions and Answers on Aminoadipate Semialdehyde Synthase in "MISCELLANEOUS»UNFILED"
What is Aminoadipate Semialdehyde Synthase?
Aminoadipate Semialdehyde Synthase (or AASS) is an enzyme involved in the lysine biosynthesis pathway. AASS catalyzes the formation of aminoadipate semialdehyde from l-glutamate and acetyl-CoA in the presence of Mg2+ cofactors.
What does AASS do?
AASS catalyzes two consecutive steps in the lysine biosynthesis pathway, first converting L-glutamate and acetyl-CoA to aminoadipate semialdehyde, then aminoadipate semialdehyde to saccharopine.
How does AASS work?
AASS works by catalyzing a reaction between L-glutamate and acetyl CoA with the help of magnesium ions as a cofactor to form aminoadipate semialdehyde. It then proceeds by catalyzing the conversion of aminoadipate semialdehyde to saccharopine.
What is the role of magnesium ions in AASS activity?
Magnesium ions (Mg2+) are essential for proper functioning of Aminoadipate Semialdehyde Synthase (AASS). They provide stability to the enzyme structure as well as assist with substrate binding and catalysis.
