Sulfodiicoccus acidophilus HS-1（T）是Sulfodiicoccus属的模式种，一种嗜热嗜酸古菌，属于Sulfolobales（Thermoprotei纲; Crenarchaeota门）。而S.嗜酸菌HS-1（T）的16 S rRNA基因序列与硫化叶菌目其它物种的16 S rRNA基因序列相似性小于89%。为了了解S.结果嗜酸链球菌HS-1（T）的环状基因组为100 bp，与Sulfolobales（Sulfolobales）的环状基因组相似。HS-1（T）全长2353，189 bp，G+C含量为51.15mol%。共预测了2459个基因，其中蛋白质编码基因2411个，RNA基因48个。对S.与嗜酸菌HS-1（T）在Sulfolobales物种中的差异在于polB 3和自养碳固定途径基因的缺失，以及与基因组复制起始相关的必需基因和序列的分布模式。这些见解有助于了解古细菌基因组多样性和进化。
ObjectiveSulfodiicoccus acidiphilus HS-1(T) is the type species of the genus Sulfodiicoccus, a thermoacidophilic archaeon belonging to the order Sulfolobales (class Thermoprotei; phylum Crenarchaeota). While S. acidiphilus HS-1(T) shares many common physiological and phenotypic features with other Sulfolobales species, the similarities in their 16S rRNA gene sequences are less than 89%. In order to know the genomic features of S. acidiphilus HS-1(T) in the order Sulfolobales, we determined and characterized the genome of this strain.ResultsThe circular genome of S. acidiphilus HS-1(T) is comprised of 2353,189bp with a G+C content of 51.15mol%. A total of 2459 genes were predicted, including 2411 protein coding and 48 RNA genes. The notable genomic features of S. acidiphilus HS-1(T) in Sulfolobales species are the absence of genes for polB3 and the autotrophic carbon fixation pathway, and the distribution pattern of essential genes and sequences related to genomic replication initiation. These insights contribute to an understanding of archaeal genomic diversity and evolution.
