TransferasesOpen in Browse
CatLog read 12 records for EC 2.3.1.33 from 1 paper, for 1 organism. Names in these papers: histidine acetyltransferase HisAT (NAT16), histidine acetyltransferase HisAT (NAT16) F63S allele (Ser63, rs34985488-G), NAT16 (histidine acetyltransferase, HisAT).
Read from the paper by an AI model and checked against the paper by a second, separate AI run; code converted the units.
CatLog also holds 2 records for EC 2.3.1.33 that are not yet re-read: from its earlier version, built from the enzyme databases and partly checked against the papers. All records for EC 2.3.1.33 in Browse.
