Diverse nifH and nifH-like gene sequences were obtained from the deep-sea surface sediments of the methane hydrate-bearing Okhotsk Sea. Some sequences formed novel families of the NifH or NifH-like proteins, of currently unresolved bacterial or archaeal origin. Comparison with other marine environments indicates environmental specificity of some of the sequences, either unique to the methane seep sediments of the Okhotsk Sea or to the general deep-sea methane seep sedimentary environments.
从鄂霍次克海含甲烷水合物的深海表层沉积物中获得了多种nifH和类nifH基因序列。一些序列形成了NifH或类NifH蛋白的新家族,其细菌或古菌起源目前尚未明确。与其他海洋环境的比较表明,其中一些序列具有环境特异性,要么是鄂霍次克海甲烷渗漏沉积物所特有的,要么是一般深海甲烷渗漏沉积环境所特有的。
