Taxonomy and molecular signatures
As of 2021, Haloferacaceae contains 10 validly published genera.[1] This family can be molecularly distinguished from other Halobacteria by the presence of five conserved signature proteins (CSPs) and four conserved signature indels (CSIs) present in the following proteins: thermosome, ribonuclease BN and hypothetical proteins.[2]
Phylogeny
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)[1] and National Center for Biotechnology Information (NCBI).[5]
