From: Kinetic modeling and exploratory numerical simulation of chloroplastic starch degradation

Haldane relation 1 [30]
Haldane relation 2 [30]
K eq 1.0 [53]
K MA 4 4.6 mM [55]
K MB 1 1.1 mM [55]
V fmax 3 ; [DPE2] = 2 μM
K MP 3 11.7 mM [55]
K MQ 1 1.1 mM [55]
K iB 2 1.0 mM [55]

  1. Concentrations A= maltose, B = arabinogalactan, P = glucose, and Q = glucosylated arabinogalactan.
  2. 1 The K M (arabinogalactan) and K M (glucosylated arabinogalactan) values were taken from the disproportionation reaction between 4-nitrophenyl-α-D-maltoheptaoside-4-6-O-ethylidene (EPS) as donor and maltotetraose as acceptor catalyzed by the cyclodextrin glycosyltransferase (CGTase) enzyme in Thermoanaerobacterium thermosulfurigenes.
  3. 2Substituted by the T. thermosulfurigenes K i, competitive (γ-cyclodextrin) value for the disproportionation reaction between EPS as donor and maltose as acceptor catalyzed by the T. thermosulfurigenes CGTase.
  4. 3Taken from the DPE1 model.
  5. 4 Taken from T. thermosulfurigenes K M (maltose) value for the disproportionation reaction between EPS as donor and maltose as acceptor catalyzed by the T. thermosulfurigenes CGTase.
  6. 5From Haldane relations 1 and 2 and values for associated kinetic constants given.
