THIS POLYMERASE REMARK 400 RETAINS POLYMERASE ACTIVITY BUT LACKS ALL EXONUCLEASE REMARK 400 ACTIVITY. BF IS A THERMOSTABLE ENZYME AND HAS AN OPTIMAL REMARK 400 TEMPERATURE FOR ACTIVITY OF 65 DEGREES CELSIUS. THE REMARK 400 PROTEIN IS HOMOLOGOUS TO ESCHERICHIA COLI DNA POLYMERASE REMARK 400 I AND THERMUS AQUATICUS (TAQ) DNA POLYMERASE. THE REMARK 400 SECONDARY STRUCTURAL ELEMENTS OF THE ENZYME HAVE BEEN REMARK 400 ASSIGNED USING THE KABSCH AND SANDER ALGORITHM ENCODED IN REMARK 400 PROCHECK AND THEN WERE NAMED TO BE CONSISTENT WITH THE REMARK 400 STRUCTURE OF THE KLENOW FRAGMENT (KF) OF ESCHERICHIA COLI REMARK 400 DNA POLYMERASE I.
