History |
| |||||||||
Remark 999 | SEQUENCE THE DNA POLYMERASE GENE WAS CLONED FROM AN ORGANISM THAT WAS CLASSIFIED AS A THERMOSTABLE ...SEQUENCE THE DNA POLYMERASE GENE WAS CLONED FROM AN ORGANISM THAT WAS CLASSIFIED AS A THERMOSTABLE STRAIN OF BACILLUS STEAROTHERMOPHILUS BY RIBOSOMAL RNA SEQUENCING. HOWEVER, THIS PARTICULAR GENE HAS MUCH GREATER HOMOLOGY WITH THE ANALOGOUS GENE FROM GEOBACILLUS KAUSTOPHILUS, UNP ACCESSION, Q5KWC1_GEOKA. |
