  • Modification

  • phosphorylated by [protein|E88978809272FAC2520DB4ABCA0554F8028F3451|WalK] on an Asp residue
  • phosphorylated by [protein|23FF4A00C36EC1B7297F51A9EF3579B41F0B7EBA|PrkC] on Thr-101, this stimulates [protein|7F340423A34CE40D1F1AA8D373F7C4B859A6496D|WalR] activity [Pubmed|26102633]
