the non-sulfur substrates exist in equilibrium with open chain forms at low acidic pH. At neutral pH, they exist predominantly as the enzymatically favorable cyclic ketimine form (in which the ring double bond is in the C=N form), while sulfur-containing cyclic ketimine substrates exist predominantly as the enzymatically unfavorable enamine form (in which the ring double bond is in the C=C form) at neutral pH |
