spinqualitylabelsall models Hammerhead ribozyme, (PDB-ID 379d) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Ribozyme (RZ) is an RNA molecule which catalyzes a chemical reaction[1]. Glucosamine-6-phosphate activated RZ (glmS RZ) is a RZ and a riboswitch which regulates genes in response to metabolites. Leadzyme is a small, artificially-made RZ which can cleave RNA in the presence of lead. For more details on leadzyme see Student Projects for UMass Chemistry 423 Spring 2012-10. Hairpin RZ and hammerhead RZ are named based on their shape[2]. Group I intron catalyzes its own selfish splicing[3]. Comparative genomic analysis revealed Twister, Twister sister, Hatchet, and Pistol [4][5].
