Krebs Nobel Prize
Krebs was awarded the Nobel Prize in 1953 for his discovery of the citric acid cycle

Krebs was awarded the medal in 1953 for his discovery of the citric acid cycle, the process by which cells convert food into energy.

He made the discovery while working at the University of Sheffield in 1937.

The lot is the latest in a series of high profile sales of Nobel Prizes. The example awarded to Leon Lederman sold for $760,000 earlier this year. The record stands at $4.7m, set for DNA scientist James Watson's Nobel Prize in 2014.

A rare 1943 Enigma machine was another highlight, realising ?�149,000 ($232,832).

It achieved an increase of 112.8% on a ?�70,000 ($109,375) estimate.

The lot is one of very few surviving machines. The majority were destroyed by the German army as the second world war drew to a close.

Another specimen sold for a record $269,000 at Bonhams earlier this year.
