Summary:
General Background

This pathway describes a fermentation of pyruvate to ethanol, a common natural pathway that is also used for the generation of alcoholic beverages and breads.

The enzyme pyruvate decarboxylase (PDC) catalyzes the key step of this pathway. This enzyme is common in higher plants and fungi, but is rare in prokaryotes, and completely absent in animals [Candy98]. The only prokaryotes in which PDC activity has been confirmed (as of 2007) are Zymomonas mobilis, Sarcina ventriculi, Clostridium botulinum, Acetobacter species and Erwinia amylovora.

While the pathway in mostly known for its occurence in yeast, it is also common in higher plants upon conditions of oxygen deprivation caused by flooding (see sucrose degradation II (sucrose synthase)).

Superpathways: superpathway of anaerobic sucrose degradation , superpathway of fermentation (Chlamydomonas reinhardtii)

Variants: pyruvate fermentation to acetate and alanine , pyruvate fermentation to acetate and lactate I , pyruvate fermentation to acetate and lactate II , pyruvate fermentation to acetate I , pyruvate fermentation to acetate II , pyruvate fermentation to acetate III , pyruvate fermentation to acetate IV , pyruvate fermentation to acetate V , pyruvate fermentation to acetate VI , pyruvate fermentation to acetate VII , pyruvate fermentation to acetate VIII , pyruvate fermentation to acetone , pyruvate fermentation to butanoate , pyruvate fermentation to butanol II , pyruvate fermentation to ethanol I , pyruvate fermentation to ethanol III , pyruvate fermentation to isobutanol (engineered) , pyruvate fermentation to lactate , pyruvate fermentation to opines , pyruvate fermentation to propionate I , pyruvate fermentation to propionate II (acrylate pathway) , superpathway of Clostridium acetobutylicum acidogenic and solventogenic fermentation , superpathway of Clostridium acetobutylicum acidogenic fermentation , superpathway of Clostridium acetobutylicum solventogenic fermentation

E2P2 systematically integrates results from three molecular function annotation algorithms using an ensemble classification scheme. For a given genome, all protein sequences are submitted as individual queries against the base-level annotation methods. The individual methods rely on homology transfer to annotate protein sequences, using single sequence (BLAST, E-value cutoff <= 1e-30, subset of SwissProt 15.3) and multiple sequence (Priam, November 2010; CatFam, version 2.0, 1% FDR profile library) models of enzymatic functions. The base-level predictions are then integrated into a final set of annotations using an average weighted integration algorithm, where the weight of each prediction from each individual method was determined via a 0.632 bootstrap process over 1000 rounds of testing. The training and testing data for E2P2 and the BLAST reference database were drawn from protein sequences with experimental support of existence, compiled from SwissProt release 15.3."
