WebHeme is the iron-containing prosthetic group of hemoglobin, myoglobin, the cytochromes, and other heme enzymes. Heme synthesis is catabolized by enzymes in the mitochondria and the cytoplasm. Pr, propionic acid group; Ac, acetic acid group; Vi, vinyl group. The vinyl group is R—CH=CH 2. WebA new and simple method was developed to detect adenosine triphosphate (ATP) by using a DNAzymeaptamer sensor. The DNAzyme used was a single-stranded DNA that could combine with hemin. The aptamer, a single, short nucleic acid sequence that can specifically bind with many targets, was an anti-ATP aptamer. Two DNA sequences were …
