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.

The prediction of protein secondary structure from sequence is routinely used whenever a new protein is cloned, and can be the first step in a tertiary structure prediction. This review summarizes the new methods that have been applied during the past year to this long-standing problem. The accuracy for a prediction of α-helices, β-sheets and coil remains at ∼65%. © 1992.
