Identification
Name: Acetylphosphate
Description:Acetylphosphate is an intermediate in taurine and hypotaurine metabolism. It is generated from sulfoacetaldehyde, converted to acetyl-CoA and acetate via phosphate acetyltransferase (EC:2.3.1.8) and acetate kinase (EC:2.7.2.1) respectively. It is also intermediate in pyruvate metabolism. It is generated from pyruvate and the formation is catalyzed by pyruvate oxidase (EC:1.2.3.3). (KEGG)

Protein Details
• Acetate kinase
General function:
Involved in kinase activity
Specific function:
Involved in the activation of acetate to acetyl CoA and the secretion of acetate. During anaerobic growth of the organism, this enzyme is also involved in the synthesis of most of the ATP formed catabolically
Gene Name:
ackA
Locus Tag:
PA0836
Molecular weight:
42.4 kDa
Reactions
ATP + acetate = ADP + acetyl phosphate.
ATP + propanoate = ADP + propanoyl phosphate.

Protein Details
• Phosphoribosylglycinamide formyltransferase 2
General function:
Involved in ATP binding
Specific function:
Catalyzes two reactions:the first one is the production of beta-formyl glycinamide ribonucleotide (GAR) from formate, ATP and beta GAR; the second, a side reaction, is the production of acetyl phosphate and ADP from acetate and ATP
Gene Name:
purT
Locus Tag:
PA3751
Molecular weight:
42.3 kDa
Reactions
