In enzymology, an aerobactin synthase (EC 6.3.2.39) is an enzyme that catalyzes the chemical reaction

4 ATP + citrate + 2 N6-acetyl-N6-hydroxy-L-lysine + 2 H2O 4 ADP + 4 phosphate + aerobactin

The 4 substrates of this enzyme are ATP, citrate, N6-acetyl-N6-hydroxy-L-lysine, and H2O, whereas its 3 products are ADP, phosphate, and aerobactin.

This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is citrate:N6-acetyl-N6-hydroxy-L-lysine ligase (ADP-forming). This enzyme is also called citrate:6-N-acetyl-6-N-hydroxy-L-lysine ligase (ADP-forming). This enzyme participates in lysine degradation.

In molecular biology, biosynthesis is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined to form macromolecules. This process often consists of metabolic pathways. Some of these biosynthetic pathways are located within a single cellular organelle, while others involve enzymes that are located within multiple cellular organelles. Examples of these biosynthetic pathways include the production of lipid membrane components and nucleotides. Biosynthesis is usually synonymous with anabolism.
