Human telomerase is a ribonucleoprotein that is minimally comprised of protein (hTERT) and RNA (hTR) components. We have applied single-molecule fluorescence two-color coincidence detection to characterize complex formation between fluorophore-labeled components in solution. By systematic labeling and in vitro assembly of hTERT, hTR and telomerase's DNA substrate, we have established that catalytically functional human telomerase comprises a stable hTERT:hTR:substrate interaction in a 1:1:1 absolute stoichiometry.

* In the version of this article initially published, parentheses were missing around covalently attached domains in fusion proteins. Also, in the first two lines of the left column of page 288, "hTERT-YFP" should have read "YFP-hTERT" for consistency with the rest of the manuscript. The errors have been corrected in the HTML and PDF versions of the article.
