描述
Adenosine 5' tetraphosphate, Ap4, is a natural nucleotide present in many biological systems. This nucleotide has been found as a constituent of the nucleotide pool present in the aqueous humor of a number of mammals and appears to act as a regulator of intraocular pressure (PMID: 14600249). AP4 may also play a significant role in the physiological regulation of vascular tone (PMID: 8599250). The plasma concentration of AP4 is in the nanomolar range. Technically adenosine tetraphosphate is condensation product of adenosine with tetraphosphoric acid at the 5' position. Acetyl coenzyme A (CoA) synthetase (EC 6.2.1.1) catalyzes the synthesis of adenosine 5'-tetraphosphate (P4A) and adenosine 5'-pentaphosphate (p5A) from ATP and tri- or tetrapolyphosphate (P3 or P4).
