The general features and genomic characteristics of gram-positive Deinococcus sp. D7000 isolated from the hadal region of Mariana Trench Challenger Deep were analyzed in this study. Deinococcus sp. D7000 has a genome consisting of 4,558,742 bp, including one chromosome and nine plasmids. This strain exhibits extracellular protease activity under low temperatures. Among 4328 protein-coding sequences (CDSs), 47 encode serine peptidases. Multiple annotation analysis was used to identify two genes encoding extracellular subtilases. In addition, three types of extracellular secretion transporter systems were found upon pathway construction and analysis. Genome analysis offers insights into the putative pathway of extracellular protease and application prospect of Deinococcus sp. D7000 in enzyme development.

革兰氏阳性奇异球菌属的一般特征和基因组特征。在这项研究中分析了从马里亚纳海沟挑战者深渊的深渊区域分离的 D7000。奇异球菌属 D7000 的基因组由 4,558,742 bp 组成，包括一条染色体和九个质粒。该菌株在低温下表现出胞外蛋白酶活性。在 4328 个蛋白质编码序列 (CDS) 中，47 个编码丝氨酸肽酶。多重注释分析用于鉴定编码细胞外枯草杆菌酶的两个基因。此外，在通路构建和分析中发现了三种类型的细胞外分泌转运系统。基因组分析为奇异球菌的胞外蛋白酶假定途径和应用前景提供了见解sp. D7000 在酶开发中。
