The FMO is a trimer of proteins, each of which contains seven bacteriochlorophyll-a molecules.    From Wordnik.com.  ["MAIN" via Steve in Google Reader] Reference

In their work, the scientists have shown that that the states of these bacteriochlorophyll-a molecules could be entangled to one another.    From Wordnik.com.  ["MAIN" via Steve in Google Reader] Reference

His team examined a bacteriochlorophyll complex found in green sulphur bacteria and discovered that the pigment molecules were similarly wired together in a quantum mechanical network.    From Wordnik.com.  [New Scientist - Online News] Reference

Chlorophyll and bacteriochlorophyll biosynthesis requires the two-electron reduction of protochlorophyllide a ringDbya protochlorophyllide oxidoreductase to form chlorophyllide a. A light-dependent (light-dependent Pchlide oxidoreductase (LPOR)) and an unrelated dark operative enzyme (dark operative Pchlide oxidoreductase (DPOR)) are known.    From Wordnik.com.  [Journal of Biological Chemistry current issue] Reference
