WitrynaLeghemoglobins (Lb) are small monomeric heme pro- teins found in root nodules of leguminous plants. These proteins have unusually high affinities for oxygen com- pared to vertebrate myoglobins and hemoglobins. The association rate constants for O 2 binding are very large (1 × 10 8 to 3 × 10 M −1 s −1 Witryna29 lis 2024 · Hemoglobins (Hbs) represent a large family of globular proteins that exist in nearly all organisms, from bacteria to higher eukaryotes [ 1 ], and participate in a broad variety of biological functions. Most of these functions are tightly associated with the prosthetic heme iron reactivity towards small ligands, especially oxygen.
