7.3.2.7 | Trypsin |
trypsin cleaves the ArsA at Arg290 to produce a 32 kDa A1 fragment that is catalytically inactive and remains stable to trypsin digestion, and a slightly smaller A2 fragment which is digested rapidly. The trypsin digestion pattern is much different when all three ligands, ATP, Sb(III), and Mg2+, are added together, conditions that produce activated catalysis, overview |
