Granules filled with this element are found in Actinomyces israelii. The TP
Granules filled with this element are found in Actinomyces israelii. The TPST enzyme isresponsible for adding a group containing this element to tyrosine. A radical on this element is foundin the active site of ribonucleotide reductase. PDI catalyzes the formation of bonds between twoatoms of this element, which in aconitase forms an active site cluster with iron. Its 35 isotope wasused in the Hershey-Chase experiment to label (*) proteins. The chemoautotrophic bacteria living neardeep sea vents use a compound of this element as an energy source. The side chain of cysteine contains thiselement, allowing it to form a type of bridge important in secondary structure stability. For 10 points, namethis element found in thiol groups, with symbol S.
