@gbolduev All of those diseases have elevated histamine production. That's why histidine is low. HDC is upregulated because immune system is stuck in a positive feedback loop due to stimulus from oxidative damage. Low histidine is a symptom.
If we are just going to name off molecules that have histidine in the their structure, we are going to have a long list because it's in everything. More important and targeted question are:
- Is histidine essential for the activity of enyzme that produces that hormone/vitamin/function?
- Is histidine in the active site of the hormone/enzyme?
- Is there another limiting factor that's more important than histidine? As an example, conversion of proinsulin to insulin is dependent on intracellular acidic pH. So if a person is in alkalosis, insulin levels will be down whether or not histidine is there or not.
