TransferasesOpen in Browse

CatLog read 18 records for EC 2.3.1.258 from 2 papers, for 2 organisms. Names in these papers: Naa50p (hNaa50p, Nat5/San; N-alpha-acetyltransferase), Nalpha-acetyltransferase Ard1 (SsArd1).

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 9 records for EC 2.3.1.258 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 2.3.1.258 in Browse.
