Definition of argI

• Curated proteins or TIGRFams with EC 2.1.3.3
• Ignore hits to items matching EC 2.1.3.6 when looking for 'other' hits
• Comment: ArgI converts ornithine to citrulline. (E. coli has two paralogs, argI and argF.) Some putrescine carbamoyltransferases (EC 2.1.3.6) are also active on ornithine (Q837U7) so any similarity to those is ignored.
