Clan 5 is the clan that holds many of the historical bacterial "type I" l‑asparaginases as well as l‑asparaginases from fungi and metazoans, including humans.
Family 15 is similar to Family 14, as most of the sequences also contain ankyrin repeats, however, these l‑asparaginases are mostly of fungal origin and lack the extra alpha helix. Many AlphaFold structures seem to have an additional beta sheet instead. At least one protein was studied experimentally: the Rhizomucor miehei RmAI (W0G253) with a relatively high affinity to l‑asparagine and negligible l‑glutaminase activity.
