This insight could be translated to understand the more complex analogue of photosynthesis in cyanobacteria[12] which is essentially the same as that in chloroplasts of higher plants.

[2] His certificate of election reads: Huber has built up, led and still leads the most productive protein crystallography laboratory in Europe.

For his PhD thesis he solved the chemical formula of the important insect hormone edtyson which had eluded the chemists.

Huber's structure of citrate synthase revealed a striking example of a conformational change undergone by an enzyme on combination with its substrate by a process of induced fit.

Huber shared the Nobel Prize for Chemistry in 1988 with Michel and Deisenhofer for their determination of the remarkable and supremely important structures of the photochemical reaction centre of Rhodopseudomonas viridis and of phycocyanin, the light harvesting protein of the blue-green alga Mastiglocadus laminosus.

This protein binds linear tetrapyrroles in a tertiary fold reminiscent of the globins, which brought Huber back full circle to his first structure, erythrocruerin, Huber has also determined the structures of several copper-containing electron-transfer proteins, including that of ascorbate oxidase, and of other metallo-enzymes.
