Name: Adenosine 3',5'-diphosphate
Description:Adenosine 3', 5'-diphosphate or PAP is a nucleotide that is closely related to ADP. It has two phosphate groups attached to the 5' and 3' positions of the pentose sugar ribose (instead of pyrophosphoric acid at the 5' position, as found in ADP), and the nucleobase adenine. PAP is converted to 3'-phosphoadenosine 5'-phosphosulfate (PAPS) by Sulfotransferase and then back to PAP after the sulfotransferase reaction. Sulfotransferase (STs) catalyze the transfer reaction of the sulfate group from the ubiquitous donor 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to an acceptor group of numerous substrates. This reaction, often referred to as sulfuryl transfer, sulfation, or sulfonation plays a key role in various biological processes such as cell communication, growth and development, and defense. (HMDB) PAP is involved in sulfur metabolism in Pseudomonas aeruginosa, and can be converted into AMP and subsequently ADP by enzymes. (PMID 10939241)
