Figure 4.

Library comparisons based on gene ontology Molecular Function assignments. X axis: library (as listed in Table 1). Y axis, GO function: 1. chaperone regulator activity, 2. triplet codon-amino acid adaptor activity, 3. protein tag, 4. energy transducer activity, 5. chemoattractant activity, 6. chemorepellant activity, 7. nutrient reservoir activity, 8. motor activity, 9. signal transducer activity, 10. enzyme regulator activity, 11. antioxidant activity, 12. translation regulator activity, 13. transcription regulator activity, 14. structural molecule activity, 15. transporter activity, 16. molecular function unknown, 17. binding, 18. catalytic activity. Z axis: percentage of ESTs with known GO molecular function in each library, calculated as number of ESTs with GO assignments/total number of EST in each library.
