== Reaction ==
If you would like use the '''MathML''' rendering mode, you need a wikipedia user account that can be registered here [[https://en.wikipedia.org/wiki/Special:UserLogin/signup]]
* Only registered users will be able to execute this rendering mode.
* Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.


Glycine dehydrogenase (decarboxylating) ({{EC number|1.4.4.2}}) is an [[enzyme]] that [[catalysis|catalyzes]] the following [[chemical reaction]]:
Registered users will be able to choose between the following three rendering modes:  


:glycine + H-protein-lipoyllysine <math>\rightleftharpoons</math> H-protein-S-aminomethyldihydrolipoyllysine + CO<sub>2</sub>
'''MathML'''
:<math forcemathmode="mathml">E=mc^2</math>


Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[glycine]] and H-protein-lipoyllysine, whereas its two [[product (chemistry)|products]] are H-protein-S-aminomethyldihydrolipoyllysine and [[carbon dioxide|CO<sub>2</sub>]].
<!--'''PNG'''  (currently default in production)
:<math forcemathmode="png">E=mc^2</math>


This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-NH2 group of donors with a disulfide as acceptor.  This enzyme participates in glycine, serine and threonine metabolism.  It employs one [[cofactor (biochemistry)|cofactor]], [[pyridoxal phosphate]].
'''source'''

== Function ==
<span style="color: red">Follow this [https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-rendering link] to change your Math rendering settings.</span> You can also add a [https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-rendering-skin Custom CSS] to force the MathML/SVG rendering or select different font families.

Glycine decarboxylase is a P-protein of the [[glycine cleavage system]] in [[eukaryotes]].  The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its [[pyridoxal phosphate]] cofactor. Carbon dioxide is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein.
==Demos==


Degradation of glycine is brought about by the glycine cleavage system, which is composed of four mitochondrial protein components: P protein (a pyridoxal phosphate-dependent glycine decarboxylase), H protein (a lipoic acid-containing protein), T protein (a tetrahydrofolate-requiring enzyme), and L protein (a lipoamide dehydrogenase).<ref name="entrez"/>

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:
