| Term | Definition |
|---|
| kinase | allows nuclosides to be synthesized into nucleotides and nucleotide tri-phosphates (NRPPP) (s) |
| nucleotidase | break NRPPP back down to nucleoside (s) |
| phosphorylase | takes nucleosides, cleaves bases, and produces ribose (1) Phosphate (s) |
| PRPP transferase | salvages bases allows re-introduction of sugar and phosphate in one step (1) |

| deaminase | takes an amino group from base, nucleotide, or nucleoside |
| deaminase | takes sidechains of N, NR, or NRP |
