- Abstract
- The amino-acid sequences of glycolytic enzymes were used to determine the evolutionary relationships between organisms. Glycolytic enzymes are suitable evolutionary chronometers, because they are ubiquitously present. Moreover, their evolution rate is sufficiently slow to enable their use for tracing overall patterns of evolution, but still fast enough to use them for the precise classification of closely related organisms. Our analysis has revealed several examples of horizontal gene transfer between organisms. Some of these transfers can be attributed to the endosymbiotic origin of plastids in plants and the subsequent migration of DNA from the prokaryotic genome of the organelle to the plant nucleus. However, other examples of putative gene transfer involve non-phototrophic organisms; in these latter cases other transfer mechanisms should be invoked. Some anomalies in phylogenetic trees remain so far unexplained. Metabolic constraints or additional functions for glycolytic enzymes may have influenced the direction and rate of evolution of glycolytic enzymes in some organisms.
