Platypus, Save Us!

The weird egg lay­ing mam­mal with a duck’s bill on its face may hold the key to the prob­lem of our antibi­otics not work­ing well against resis­tant bac­te­ria and germs. Via Sky News:

A break­through by Aus­tralian sci­en­tists has found that the platy­pus — which is already a unique crea­ture — is also in pos­ses­sion of fairly unique biochemistry.

Researchers from the Com­mon­wealth Sci­en­tific and Indus­trial Research Organ­i­sa­tion (CSIRO) and Deakin Uni­ver­sity have dis­cov­ered a spe­cial pro­tein con­tained in platy­pus milk.

CSIRO sci­en­tist and lead author Dr Janet New­man said: “Platy­pus are such weird ani­mals that it would make sense for them to have weird biochemistry.

The platy­pus belongs to the monotreme fam­ily, a small group of mam­mals that lay eggs and pro­duce milk to feed their young.

By tak­ing a closer look at their milk, we’ve char­ac­terised a new pro­tein that has unique antibac­te­r­ial prop­er­ties with the poten­tial to save lives.”

The study, pub­lished in Struc­tural Biol­ogy Com­mu­ni­ca­tions, finds that the way platy­pus moth­ers feed their young — which unusu­ally for mam­mals hatch from eggs — has led to the antibac­te­r­ial prop­er­ties developing.

Platy­pus do not have teats, but instead express milk on to their belly where the young suckle it — mean­ing the milk becomes exposed to an envi­ron­ment where it could be con­t­a­m­i­nated by local bacteria.

Evo­lu­tion­ary processes have meant that the milk con­tains a spe­cial pro­tein which pro­tects the platy­pus babies against this bacteria.

Dr Julie Sharp of Deakin Uni­ver­sity said: “We were inter­ested to exam­ine the protein’s struc­ture and char­ac­ter­is­tics to find out exactly what part of the pro­tein was doing what.”

They found that the pro­tein con­tained a unique 3D fold which had never been seen before in the struc­ture of the molecule.

A breakthrough by Australian scientists has found that the platypus – which is already a unique creature – is also in possession of fairly unique biochemistry.

Researchers from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Deakin University have discovered a special protein contained in platypus milk.

CSIRO scientist and lead author Dr Janet Newman said: “Platypus are such weird animals that it would make sense for them to have weird biochemistry.

“The platypus belongs to the monotreme family, a small group of mammals that lay eggs and produce milk to feed their young.

“By taking a closer look at their milk, we’ve characterised a new protein that has unique antibacterial properties with the potential to save lives.”

The study, published in Structural Biology Communications, finds that the way platypus mothers feed their young – which unusually for mammals hatch from eggs – has led to the antibacterial properties developing.

Platypus do not have teats, but instead express milk on to their belly where the young suckle it – meaning the milk becomes exposed to an environment where it could be contaminated by local bacteria.

Evolutionary processes have meant that the milk contains a special protein which protects the platypus babies against this bacteria.

Dr Julie Sharp of Deakin University said: “We were interested to examine the protein’s structure and characteristics to find out exactly what part of the protein was doing what.”

They found that the protein contained a unique 3D fold which had never been seen before in the structure of the molecule.
