Abstract:

I feel honoured by the invitation of the National Academy of Sciences to preside over this year’s Biological Sciences Section, specially as I have never had any formal training – not even at the school level – in any area of biology. When 1 received – and accepted – this invitation, I reckoned I had three choices: I could (a) talk a little about many things that is, present a synopsis or a survey and try to cover up my ignorance, or (b) present an in – depth review in one particular area and reveal my ignorance, or (c) talk in Some depth about an area of my own interest and share with you my follies and failures. I have decided to take recourse to the last -mentioned of the choices, as I take it I have been invited here in my capacity as a working scientist of the present.

One area in which I have had an interest for the last nearly quarter of a century, is biochemistry of semen. Certain exotic aspects of semen are known to everyone, and I am no greater expert in regard to them than anyone of you. It is about the non-exotic aspects of this exotic material that I wish to talk to you today. In fact, what I, really wish to tell you about is the discovery of four unusual proteins I contained in bovine seminal fluid which, put together, have a strikingly unusual set of properties. These proteins have been named by us as ‘seminalplasmin’ ‘antiseminalplasmin’ ‘ribonuclease SPL’ and ‘protease SPL’. This, I realise, may not be quite as exotic as the title of this talk, but then, today. I suppose one can build a case for the titles of scientific papers to be like our cinema posters. There is a lot there that is not insidel.

In talking about the above four proteins, I would like to present to you first the historical background of their discovery, and then say something about their isolation and properties, both physical and biological.
