Molecule List for pathway MAPK (Pathway Number 56) in Accession 3d_fold_model (Accession Number 8)

Default ordering is done according to Pathway Number. Table headers can be used for changing the default ordering.
arrow indicates that ordering is done according to ascending or descending order.
The entries are grouped according to Pathway Number and are alternately color coded using  and  color.

BufferedSum Total Of
1 craf-1Network0.21000No
    Couldn't find any ref to the actual conc of craf-1 but I should try Strom et al Oncogene 5 pp 345 In line with the other kinases in the cascade, I estimate the conc to be 0.2 uM. To init we use 0.15, which is close to equil
2 craf-1*Network01000No
3 craf-1**Network01000No
    Negative feedback by MAPK* by hyperphosphorylating craf-1* gives rise to this pool. Ueki et al JBC 269(22):15756-15761, 1994
4 MAPKNetwork0.361000No
    conc is from Sanghera et al JBC 265 pp 52 (1990) A second calculation gives 3.1 uM, from same paper. They est MAPK is 1e-4x total protein, and protein is 15% of cell wt, so MAPK is 1.5e-5g/ml = 0.36uM. which is closer to our first estimate. Lets use this.
5 MAPK-tyrNetwork01000No
    Haystead et al FEBS Lett. 306(1) pp 17-22 show that phosphorylation is strictly sequential, first tyr185 then thr183.
6 MAPKKNetwork0.181000No
    Conc is from Seger et al JBC 267:20 pp14373 (1992) mwt is 45/46 Kd We assume that phosphorylation on both ser and thr is needed for activiation. See Kyriakis et al Nature 358 417 1992 Init conc of total is 0.18
7 MAPKK*Network01000No
    MAPKK phosphorylates MAPK on both the tyr and thr residues, first tyr then thr. Refs: Seger et al JBC267:20 pp 14373 1992 The MAPKK itself is phosphorylated on ser as well as thr residues. Let us assume that the ser goes first, and that the sequential phosphorylation is needed. See Kyriakis et al Nature 358 417-421 1992
8 MAPKK-serNetwork01000No
    Intermediately phophorylated, assumed inactive, form of MAPKK
9 Raf-GTP-Ras*Network01000No
