THE MACROMOLECULAR ELECTROSTATIC EFFECT IN BIOCHEMICAL OF ~EACTIVITY THE NUCLEIC ACIDS.

INTRODUCTION The roLe of the macromoLecuLe and of its overaLL structure upon the reactivity of its reaction site(s) represents one of the fundamentaL probLems in the theory of cataLysis. The most impressive and most fre quentLy considered exampLes occur in the fieLd of proteins where the probLem generaLLy consists of accounting for the enhancement of the reaction rate at the active site or at the coenzyme with respect to modeL systems, devoid of the macromoLecuLar superstructure. Different effects have been considered as possibLy responsibLe for the infLuence of the macromoLecuLe on such LocaLized-site reactions. I do not have the time to summarize or discuss them here. I wouLd Like, however, to underLine the accent put recentLy in a number of studies, on the possi bLy primordial role in this respect of the electrostatic effect of the protein on its specific reactivities. Examples of such considerations may be found in the work of Hayes and Kollman on carboxypeptidase A [1][2], in the work of Warshel on lysozyme [3][4], in the work of Van Duijnen on the role of the a-helix dipole on the reactional properties of proteins, in particular papain [5][6] etc. (For generaL comments see also [7]). The different authors differ in the details of their approach, but have in common to Limit their consideration to proteins. It is, however, evident that similar effects may be conside red aLso for other types of biopolymers in particular for nucLeic acids in which it appears legitimate to ask what is the infLuence of the overall macromoLecular structure of, say DNA, upon the properties of the different reaction sites of, say, its purine and pyrimidine bases. It is this problem that we wish to treat here. I would like to state immediately that we shalL limit ourselves to consider only the eLectrostatic aspect of this influence and shalL neglect, for the while being, other possible aspects. This restriction introduces a se vere limitation if we wish to compare the resuLts of computations with experimental findings (vide infra). However, in as much as it may be estimated that the electrostatic effect is an important one, the study is obviously of interest if onLy as a step towards a more complete ex- B.

THE ELECTROSTATIC MOLECULAR POTENTIAL For the sake of expLoring the eLectrostatic effect of the macromoLecu Lar structure of DNA upon the properties of its purine and pyrimidine bases we shaLL use the notion of the eLectrostatic moLecuLar potentiaL, about which Madame PuLLman has Lectured aLready here at a previous m. JerusaLem Symposium [ May I remind that under this denomination we consider the eLectrostatic potentiaL created in the neighbouring space by the nucLear charges and the electronic distribution of the system. For a given wave function with the corresponding first order density function p(i) the average vaLue of such a potentiaL V(P) at a given point P in space is given by [9] V(P) = 1: ~ _ p(;) de. a raP rpi 1 where Z is the nucLear charge of nucLeus a. This quantity has the ad vantageaof being directLy obtainabLe from the wave function and thus does not suffer from the drawbacks inherent in the cLassicaL popuLa tion anaLysis. Moreover its very definition makes it an interesting index for the study of chemicaL reactivity at Least in the earLy stage of approach of an ionic reagent. Thus the interaction energy between the moLecuLar eLectronic distribution (considered unperturbed) and an externaL point charge q pLaced at point P is qV(P), which is rigou rousLy the first order perturbation energy of the moLecuLe in the fieLd of charge q. Taking q as a unit positive charge the interaction potentiaL can be used directLy for the study of proton affinities. (See e.g. [10-12] for such a study of the nucLeic acid bases). Its utiLiza tion for the investigation of the interaction of the Ligands with more compLex cations such as metaL or aLkyL cations is subject to caution because of the increased importance in such cases of the compLementary components of the binding energy (besides the pureLy couLombic one) nameLy the delocaLization (poLarization + charge transfer) and the ex change components. The probLem has been investigated expLicitLy in our Laboratory in reLation with the interaction of the nucLeic acid bases with Na+ [13], Mg++ [14] and aLso with aLkyL cations [15] • With this (important) restriction in mind we wouLd Like to investigate, as the first stage of the expLoration of the effect of the macromoLecuLar superstructure, the modifications in the moLecuLar potentiaLs of the individuaL bases brought about by their pairing through hydrogen bonding in the Watson-Crick compLementary scheme of DNA : adenine-thymine and guanine-cytosine. The usuaL way of represen~ ting these potentiaLs is, as is weLL known, through the utilization of the eLectrostatic isopotentiaL maps. Here we shaLL center our atten tion essentiaLLy on the regions surrounding the minima of the poten tiaLs in the most attractive regions, which are situated in the isoLa ted bases in the moLecuLar pLane in the neighbourhood of N1, N3 and N7 of adenine, N7, 06, N3 of guanine, N1, 02 of cytosine and 04' 02 of thymi ne (i n the order i ndi cated for eacti base).
