ENTRY       EC 6.5.1.4
NAME        RNA-3'-phosphate cyclase
            RNA cyclase
CLASS       Ligases
            Forming phosphoric ester bonds
SYSNAME     RNA-3'-phosphate:RNA ligase (cyclizing, AMP-forming)
REACTION    ATP + RNA 3'-terminal-phosphate = AMP + Pyrophosphate +
            RNA terminal-2',3'-cyclic-phosphate
SUBSTRATE   ATP
            RNA 3'-terminal-phosphate
            Adenosine 5'-(gamma-thio)triphosphate
PRODUCT     AMP
