In enzymology, a gamma-guanidinobutyraldehyde dehydrogenase (EC 1.2.1.54) is an enzyme that catalyzes the chemical reaction

4-guanidinobutanal + NAD⁺ + H₂O 4-guanidinobutanoate + NADH + 2 H⁺

The 3 substrates of this enzyme are 4-guanidinobutanal, NAD⁺, and H₂O, whereas its 3 products are 4-guanidinobutanoate, NADH, and H⁺. Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins This article is about the Enzyme Commission codes For the European Commission system for coding chemicals see EC-No. Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins Catalysis is the process in which the rate of a Chemical reaction is increased by means of a Chemical substance known as a catalyst A chemical reaction is a process that always results in the interconversion of Chemical substances The substance or substances initially involved in a chemical reaction are called Nicotinamide adenine dinucleotide, abbreviated NAD+, is a Coenzyme found in all living cells The compound is a dinucleotide since it consists Water is a common Chemical substance that is essential for the survival of all known forms of Life. A product is a substance that forms as a result of a Biological - or Chemical reaction. Nicotinamide adenine dinucleotide, abbreviated NAD+, is a Coenzyme found in all living cells The compound is a dinucleotide since it consists Hydrogen ion is recommended by IUPAC as a general term for all Ions of Hydrogen and its Isotopes Depending on the Charge of the ion

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. In Biochemistry, an oxidoreductase is an Enzyme that catalyzes the transfer of Electrons from one molecule (the reductant, also called the hydrogen The systematic name of this enzyme class is 4-guanidinobutanal:NAD+ 1-oxidoreductase. Other names in common use include alpha-guanidinobutyraldehyde dehydrogenase, 4-guanidinobutyraldehyde dehydrogenase, and GBAL dehydrogenase. This enzyme participates in urea cycle and metabolism of amino groups. The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions occurring in many animals that produces Urea ( N[[hydrogen
