Accession No. : 8 | PLA2
Pathway No. : 57 | 0.4 | 1000 | No | | Calculated cytosolic was 20 nm from Wijkander and Sundler However, Leslie and Channon use about 400 nM. Need to confirm, but this is the value I use here. Another recalc of W&S gives 1uM |

| | Km = 25uM @ 50 uM ATP and 1mg/ml MBP (huge XS of substrate) Vmax = 4124 pmol/min/ml at a conc of 125 pmol/ml of enz, so: k3 = .5/sec (rate limiting) k1 = (k2 + k3)/Km = (.5 + 0)/(25*6e5) = 2e-8 (#/cell)^-1 #s from Sanghera et al JBC 265 pp 52 , 1990. From Nemenoff et al JBC 268(3):1960-1964 - using Sanghera's 1e-4 ratio of MAPK to protein, we get k3 = 7/sec from 1000 pmol/min/mg fig 5 |
PLA2-cytosolic acting as a Substrate in a reaction in 3d_fold_model Network
| Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated.
Kd for higher order reaction are not consider. |
