INMT

that's pretty awesome looking data. wish I could make sense from it.

what does this mean in your line of work? is this new research/data?

Benzy, more importantly, can you tell what's going on simply by looking at a huge chunk of text like that?

And can you please decant... I mean... elaborate further?

it's not new data, but it is well referenced.
the protein sequence can be compared to other sequences in other organisms, this is called homology.

the mRNA sequence is basically the coding for the gene of INMT expression.

Noncompetitive Inhibition of Indolethylamine-N-methyltransferase by N,N-Dimethyltryptamine and N,N-Dimethylaminopropyltryptamine.

Abstract:
Indolethylamine-N-methyltransferase (INMT) is a Class 1 transmethylation enzyme known for its production of N,N-dimethyltryptamine (DMT), a hallucinogen with affinity for various serotonergic, adrenergic, histaminergic, dopaminergic, and sigma-1 receptors.

DMT is produced via the action of INMT on the endogenous substrates tryptamine and S-adenosyl-l-methionine (SAM). The biological, biochemical, and selective small molecule regulation of INMT enzyme activity remain largely unknown.

Kinetic mechanisms for inhibition of rabbit lung INMT (rabINMT) by the product, DMT, and by a new novel tryptamine derivative were determined. After Michaelis-Menten and Lineweaver-Burk analyses had been applied to study inhibition, DMT was found to be a mixed competitive and noncompetitive inhibitor when measured against tryptamine.

The novel tryptamine derivative, N-[2-(1H-indol-3-yl)ethyl]-N',N'-dimethylpropane-1,3-diamine (propyl dimethyl amino tryptamine or PDAT), was shown to inhibit rabINMT by a pure noncompetitive mechanism when measured against tryptamine with a Ki of 84 μM. No inhibition by PDAT was observed at 2 mM when it was tested against structurally similar Class 1 methyltransferases, such as human phenylethanolamine-N-methyltransferase (hPNMT) and human nicotinamide-N-methyltransferase (hNNMT), indicating selectivity for INMT.

The demonstration of noncompetitive mechanisms for INMT inhibition implies the presence of an inhibitory allosteric site. In silico analyses using the computer modeling software Autodock and the rabINMT sequence threaded onto the human INMT (hINMT) structure (Protein Data Bank entry 2A14 ) identified an N-terminal helix-loop-helix non-active site binding region of the enzyme. The energies for binding of DMT and PDAT to this region of rabINMT, as determined by Autodock, were -6.34 and -7.58 kcal/mol, respectively. Assessment of the allosteric control of INMT may illuminate new biochemical pathway(s) underlying the biology of INMT

Here is the amino acid sequence for the human 5HT2A receptor, in case anyone needs it:

I even made a fancy picture with I-TASSER

Question: how hard is it to insert the genes for a specific metabolic pathway into an organism that doesn't naturally express them?

It appears to be just 3 metabolic steps from L-tryptophan to DMT, so that means that, in theory, at least, we just need to insert the codes for 3 different enzymes into the genetic sequence.

What if we could do that for some kind of fast-growing, easy-to-care-for fungus (think like wood-ear mushrooms, you can buy grow-kits at the Whole Foods)? If that were the case, it would be easy and cheap to manufacture large quantities of DMT in a sustainable matter.

If we could get the sequences for other pathways that produce substituted tryptamines, there could be a whole world opening up of custom fungi.
