We found ADP - ribosylating activity for the SCO5461 protein product through its co - incubation with guanosine and NAD ( + ) , which resulted in the formation of N ( 2 ) - ( ADP - ribos - 1 - yl ) - guanosine ( ( ar2 ) Guo ) , with a K ( m ) value of 110 mu M .
 Chemical: ADP; Chemical: guanosine; Chemical: NAD ( + ); Chemical: N ( 2 ) - ( ADP - ribos - 1 - yl ) - guanosine; Chemical: ( ar2 ) Guo
