"Protein/gene_name: Vitamin B12-dependent ribonucleoside-diphosphate reductase (intein-containing); name of intein 1:Homing endonuclease PI-PfuI; name of intein 2:Homing endonuclease PI-PfuII. Function: The function of both inteins (PI-PfuI and PI-PfuII) was characterized as intein-coded homing endonuclease; they cleave double-stranded DNA with the sequence of the intein(-)allele. Comments: The two inteins are spliced out from the precursor protein."xsd:string
