Unsaturated receptor modification and imperfect adaptation (source code)

= Unsaturated receptor modification and imperfect adaptation

If the forward receptor-modification flux depends on remaining unmethylated <substrate>, it generally depends indirectly on <ligand> through the modified <receptor> pool. The steady output then need not be <ligand> independent. Near-perfect adaptation may remain in a saturation limit; finite modification capacity and completely inactive <receptor> <biological populations> also bound the ideal perfect-adaptation result.
