Enzyme List for pathway PLCbeta (Pathway Number 315) | | Molecule Name/
Site Name | Km (uM) | kcat (1/s) | Ratio
(k2/k3) | Enzyme Type | Substrate | Product |
| 1 |
Enzyme Activity:
PLC-Ca
Enzyme Molecule:
PLC-Ca | 19.8413 | 10 | 4 | explicit E-S complex | PIP2
| DAG
IP3
| | | From Sternweis et al Phil Trans R Soc Lond 1992, also matched by Homma et al. k1 = 1.5e-5, now 4.2e-6 k2 = 70/sec; now 40/sec k3 = 17.5/sec; now 10/sec Note that the wording in Sternweis et al is ambiguous re the Km. |

Enzyme Activity:
PLCb-Ca-Gq
Enzyme Molecule:
PLC-Ca-Gq | 5.00003 | 48 | 4 | explicit E-S complex | PIP2
| DAG
IP3
| | | From Sternweis et al, Phil Trans R Soc Lond 1992, and the values from other refs eg Homma et al JBC 263(14) pp6592 1988 match. k1 = 5e-5/sec k2 = 240/sec; now 120/sec k3 = 60/sec; now 30/sec Note that the wording in Sternweis et al is ambiguous wr. to the Km for Gq vs non-Gq states of PLC. K1 is still a bit too low. Raise to 7e-5 9 Jun 1996: k1 was 0.0002, changed to 5e-5 |
