Sternberg MJE, Hirst JD, Lewis RA, et al., 1994, Application of machine learning to protein structure prediction and drug design, ISSN: 0963-3308
The use of inductive-based logic programming (ILP) in predicting protein structure and drug design was discussed in this article. In the study of alpha and beta fields with alternating alpha-helices and beta-sheet strands, ILP program GOLEM was employed. GOLEM was capable of generating an inductive hypothesis based on coded facts and negative counter-example and chemical background knowledge. However, for drug design machine learning program PROLOG was applied. PROLOG can comprehend the properties of bonds and atoms. It can also give insight in the chemical principles of aromatic and heteroaromatic nitro compounds. In conclusion, machine learning ILP programs can greatly enhance biochemical developments.
King RD, Clark DA, Shirazi J, et al., 1994, Inductive logic programming used to discover topological constraints in protein structures., Proc Int Conf Intell Syst Mol Biol, Vol: 2, Pages: 219-226, ISSN: 1553-0833
This paper describes the application of the Inductive Logic Programming (ILP) program GOLEM to the discovery of constraints in the packing of beta-sheets in alpha/beta proteins. These constraints (rules) have a role in understanding the protein folding problem. Constraints were learnt for four features of beta-sheet packing: the winding direction of two sequential strands, whether two consecutive strands pack parallel or anti-parallel, whether two strands pack adjacently, and whether a beta-strand is at an edge. Investigation of the learnt constraints revealed interesting patterns, some of which were previously known, others that were novel. Novel features include the discovery: that the relationship between pairs of sequential strands is in general one of decreasing size, and that more sequential pairs of strands wind in the direction out than the direction in. We conclude that machine learning has a useful place in molecular biology as a pattern discovery tool.

Neural networks and machine learning are two methods that are increasingly being used to model QSARs. They make few statistical assumptions and are nonlinear and nonparametric. We describe back-propagation from the field of neural networks, and GOLEM from machine learning, and illustrate their learning mechanisms using a simple expository problem. Back-propagation and GOLEM are then compared with multiple linear regression (using the parameters and their squares) on two real drug design problems: the inhibition of Escherichia coli dihydrofolate reductase (DHFR) by pyrimidines and the inhibition of rat/mouse tumour DHFR by triazines. © 1993 ESCOM Science Publishers B.V.

© 1993 IEEE. Determining the quantitative structure-activity relationship (QSAR) of a related series of drugs is a central aspect of the drug design process. The machine learning program Golem from the field of inductive logic programming (ILP) applied to QSAR. ILP is the most suitable machine learning technique because it can represent the structural and relational aspects of drugs. A five-step methodology for using machine learning in drug design is presented that consists of identification of the problem, choice of a representation, induction, interpretation of results, and synthesis of new drugs.
