Creatine 56-58 creatine kinase, mitochondrial 2 Gallus gallus 94-100 7920251-4 1994 Trp-223 is responsible for a strong (18-21%) fluorescence quenching effect occurring upon formation of a transition state-analogue complex (TSAC;Mib-CK.creatine.MgADP.NO3-), and Trp-223 is probably required for the conformational change leading to the TSAC-induced octamer dissociation of Mib-CK. Creatine 152-160 creatine kinase, mitochondrial 2 Gallus gallus 145-151 7920251-4 1994 Trp-223 is responsible for a strong (18-21%) fluorescence quenching effect occurring upon formation of a transition state-analogue complex (TSAC;Mib-CK.creatine.MgADP.NO3-), and Trp-223 is probably required for the conformational change leading to the TSAC-induced octamer dissociation of Mib-CK. Creatine 152-160 creatine kinase, mitochondrial 2 Gallus gallus 289-295 8399219-6 1993 However, upon addition of MgADP plus creatine and nitrate to induce a transition-state analogue complex of the enzyme, native Mib-CK dissociated much more readily into dimers than proteinase K-digested Mib-CK. Creatine 37-45 creatine kinase, mitochondrial 2 Gallus gallus 126-132 8399219-7 1993 Furthermore, proteinase K cleavage of Mib-CK resulted in 2-11-fold decreases in the Vmax values, as well as in 6-23-fold increases in the Km values for phosphocreatine, creatine, and MgATP, whereas the Kd values for both MgATP and creatine were unaffected. Creatine 159-167 creatine kinase, mitochondrial 2 Gallus gallus 38-44 8399219-7 1993 Furthermore, proteinase K cleavage of Mib-CK resulted in 2-11-fold decreases in the Vmax values, as well as in 6-23-fold increases in the Km values for phosphocreatine, creatine, and MgATP, whereas the Kd values for both MgATP and creatine were unaffected.
