硫循环
中文名称
通路描述
硫是构成生物体最常见的六种化学元素（CHNOPS）之一。该图展示了硫化合物的生物地球化学循环，以及不同环境（大气圈、水圈和岩石圈）下不同微生物如何负责化学转化。关于硫代谢的化学反应及负责酶的信息在 map00920 中显示。化学转化以 KEGG 模块表示，包括硫还原 [MD:M00986] [KO:K16952] 由硫还原细菌和古菌将元素硫转化为硫化氢，硫化物氧化 [MD:M00985] 由硫氧化光合生物将硫化氢转化为元素硫，硫氧化 [MD:M00595 M00984] 由硫氧化化能生物将亚硫酸盐转化为硫酸盐，同化性硫酸盐还原 [MD:M00596] 由硫酸盐还原细菌和古菌，以及异化性硫酸盐还原 [MD:M00176 M00987] 由原核生物和真核生物（不包括动物）进行。
英文描述
Sulfur is one of the six most common chemical elements CHNOPS that constitute living organisms. This map shows a biogeochemical cycle of sulfur compounds and how different microorganisms are responsible for chemical transformations under different environments including atmospheric, hydrospheric and lithospheric environments. Details of chemical reactions and responsible enzymes are shown in map00920 for Sulfur metabolism. Here chemical transformations are represented by KEGG modules, including sulfur reduction [MD:M00986] [KO:K16952] from elemental sulfur to hydrogen sulfide by sulfur-reducing bacteria and archaea, sulfide oxidation [MD:M00985] from hydrogen sulfide to elemental sulfur by sulfur-oxidizing phototrophs, sulfur oxidataion [MD:M00595 M00984] from thiosulfate to sulfate by sulfur-oxidizing chemotrophs, dissimilatory sulfate reduction [MD:M00596] by sulfate-reducing bacteria and archaea, and assimilatory sulfate reduction [MD:M00176 M00987] by both prokaryotes and eukaryotes excluding animals.
