Prediction of protein interactions: metabolic enzymes are frequently involved in gene fusion

Nature Genetics volume 26, pages 141–142 (2000)Cite this article

We have investigated the prediction of protein interactions through the analysis of domain fusion to assess whether metabolic enzymes have a higher participation in gene-fusion events compared with other proteins. We show here that known metabolic enzymes from Escherichia coli exhibit a threefold preference in participating in fusion events compared with control sets. This observation can be used in delineating the likely cellular role for proteins of unknown function detected by gene-fusion analysis.
