Is heme a peptide
WebNov 16, 2024 · A hemeprotein (or haemprotein; also hemoprotein or haemoprotein), or heme protein, is a protein that contains a heme prosthetic group. They are a very large class of metalloproteins. The heme group confers functionality, which can include oxygen carrying, oxygen reduction, electron transfer, and other processes. What is heme in hemoglobin? WebHemes are found in a wide variety of proteins that serve biological functions from gas transportation (e.g., hemoglobin, myoglobin) and sensing (e.g., FixL, sGC), to electron transfer (e.g., bc1 complex, cytochrome c) and complex chemical catalysis (e.g., terminal oxidases, P450s, peroxidases).
