Accession and Pathway Details | |
| Accession Name | Accession No. | Accession Type | Pathway Link | | Chemotaxis | 57 | Pathway |
Chemotaxis | Reactions feeding into TnWa, TaWA and TWA are scaled by 10 Binding reaction of Tar with Aspartate has been scaled by 10 Phosphotransfer from CheAp to CheY has Kb = 0.263/sec/uM instead of 0.2/sec/uM used in BCT1.1.
All remaining parameters are from the .BCT files for BCT1.1 provided by Matthew Levin from the Computational Biology Group in the Department of Zoology at the University of Cambridge.
The June 2003 version of the BCT program is BCT4.3 and is available at the computational biology site of the Zoology department at Cambridge University.

CheAp acting as a Substrate in a reaction in Chemotaxis 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. |
