This ''hand-like'' <scene name='Reverse_transcriptase/Chains/2'>heterodimer</scene> protein that has an usual length of 1000 residues (560 in Chain A and 440 for B), the third of them involved in alpha helical and almost a quarter in beta sheets, showing α+β <scene name='Reverse_transcriptase/Secondary/2'>secondary structure</scene> domains; <scene name='Reverse_transcriptase/Chaina/2'>Chain A</scene> has an usual weight of 66KDa whereas <scene name='Reverse_transcriptase/Chainb/2'>Chain B</scene> is around 51KDa, those monomers are derived from the same gen but p51 lacks the aminoacids of one active site and has a different tertiary structure conformation compared with p66, for this reason is totally inactive. | This ''hand-like'' <scene name='Reverse_transcriptase/Chains/2'>heterodimer</scene> protein that has an usual length of 1000 residues (560 in Chain A and 440 for B), the third of them involved in alpha helical and almost a quarter in beta sheets, showing α+β <scene name='Reverse_transcriptase/Secondary/2'>secondary structure</scene> domains; <scene name='Reverse_transcriptase/Chaina/2'>Chain A</scene> has an usual weight of 66KDa whereas <scene name='Reverse_transcriptase/Chainb/2'>Chain B</scene> is around 51KDa, those monomers are derived from the same gen but p51 lacks the aminoacids of one active site and has a different tertiary structure conformation compared with p66, for this reason is totally inactive. <ref>PMID: 1377403</ref> <!-- [http://www.sciencemag.org.silk.library.umass.edu:2048/cgi/content/abstract/sci;256/5065/1783?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&andorexacttitleabs=and&andorexactfulltext=and&searchid=1&FIRSTINDEX=0&volume=256&firstpage=1783&resourcetype=HWCIT] --> | ||
