3.4.21.43
C241A
C2 mutation, behaves similarly to the wild-type enzyme with slightly elevated hemolytic activity
695326
3.4.21.43
Q243G
C2 mutation reduces C4b2a sensitivity to decay-accelerating factor DAF to 2% of the wild-type, moderately reduces C4b2a sensitivity to complement receptor 1-A to 55% of the wild-type
