malfunction
mutational analysis of Mp mimosinase reveals that the disruption of a disulfide bond in the vicinity of the pyridoxal 5'-phosphate domain increases the enzyme's preference toward cystathionine
metabolism
physiological function
mimosinase is an important enzyme especially in the context of metabolic engineering of plant secondary metabolite as it catalyzes the degradation of mimosine, which is a toxic secondary metabolite found in all Leucaena and Mimosa species
additional information
the carbon-nitrogen lyase catalyzes the first step of mimosine degradation. Mimosine is a toxic nonprotein aromatic amino acid
metabolism
molecular relationship between mimosinase and cystathionine beta-lyase (CBL, UniProt ID A0A0M3VI47, EC 4.4.1.13). The recombinant Mp mimosinase degrades both mimosine and cystathionine with a much higher turnover number for mimosine compared with cystathionine, and Mp CBL utilizes only cystathionine as a substrate
homology modeling and molecular dynamics simulations of Mp mimosinase suggest a closer coordination of the residues that interact with mimosine at the active site compared with cystathionine, indicating a more compact pocket size for mimosine degradation, substrate docking study. Active site structure
