PME may refer to:
Protein phosphatase methylesterase-1 (EC 3.1.1.89, PME-1, PPME1) is an enzyme with system name (phosphatase 2A protein)-leucine ester acylhydrolase. This enzyme catalyses the following chemical reaction
A key regulator of protein phosphatase 2A.
Trimethylphosphine is the organophosphorus compound with the formula P(CH3)3, commonly abbreviated as PMe3. This colorless liquid has a strongly unpleasant odor, which is characteristic of alkylphosphines. The compound is a common ligand in coordination chemistry.
It is a pyramidal molecule with approximate C3vsymmetry — the molecular point group of ammonia (NH3) and phosphine (PH3). The C–P–C bond angles are approximately 98.6°.
The C–P–C bond angles are consistent with the notion that phosphorus predominantly uses the 3p orbitals for forming bonds and that there is little sp hybridization of the phosphorus atom. The latter is a common feature of the chemistry of phosphorus because the gap between the 3s and 3p orbital is large compared to the corresponding gap for the 2s and 2p orbitals that are in the valence shell for carbon, nitrogen, and oxygen (elements for which sp-mixing is strong). As a result, the lone pair of trimethylphosphine has predominantly s-character as is the case for phosphine, PH3.
There's a place in my heart where you used to be
There's a pain, deep inside, don't want the world to see
Nothing, but emptiness, once there was your caress
I was touched by your naked flame
Now, it was hard sometimes, those things that we went through
But believe me when I'd say, I would never mean to hurt you
I hold the memory of holding you next to me
In my arms like a naked flame
Think it over before you break my heart
Think it over before the crying starts
Then we can say goodbye to the tears
I should have known that this time was a coming
But if you ever need me, I'll come a running home to you
There's a place in my dreams where we used to meet
But there's no one around now, it's just an empty street
I hold the memory of holding you close to me
In my arms, like a naked flame
