Web7 nov. 2024 · Prosthetic groups help proteins bind other molecules, act as structural elements, and act as charge carriers. An example of a prosthetic group is heme in hemoglobin, myoglobin, and cytochrome. The iron (Fe) found at the center of the heme prosthetic group allows it to bind and release oxygen in the lung and tissues, respectively. WebIn eukaryotes, this transporter participates in the delivery of molybdate into cells for incorporation into molybdopterin-cofactor (Moco), the biologically active prosthetic group in molybdenum-dependent enzymes (Schwarz et al. 2009). MoT 2 transport of molybdate is inhibited by sulfate, suggesting a common carrier for molybdate and sulfate. facehubliveWebThe cofactors which are organic chemicals are known as a coenzyme.
