Miracle? I think you mean Miraculin.
 +
Miraculin is a protein that is best known for its ability to deceive human taste buds into thinking
 +
sour or acidic food is sweet. This homodimeric glycoprotein was first identified in the West
 +
African native fruit, Synsepalum dulcificum (also known as “Miracle Fruit”), and exists in the
 +
pulp of the miracle fruit.
 +
Miraculin’s deceptive properties have been exploited by several companies as sugar substitutes.
 +
However, the American Food and Drug Administration banned the use of miraculin after
 +
labeling it as an additive <ref> https://www.accessdata.fda.gov/cms_ia/importalert_120.html </ref> . This
 +
prevented its commercial use in the food industry.

== <h3><span style="color: purple;"> What We Know About Miraculin’s Structure </span> ==
 +
Miraculin is composed of 191 amino acid residues linked primarily by disulfide bonds,
 +
having a molecular weight of about 28 kDa. Sarroch Theerasil et al <ref>
 +
https://www.jbc.org/content/263/23/11536.full.pdf+html </ref> use HPLC profiles and SDS-PAGE
 +
analyses to prove this.
 +
Miraculin is a homodimer made by two chains that have two N-glycosylated Asn residues and
 +
are cross-linked through a disulfide bridge. Miraculin can also exist in a tetramer form.
