“…For example, cysteine (Cys), can potentially reduce SeO 3 2− to Se, which increases from pH 5.0-7.0, and decrease thereafter up to pH 9.0. On the contrary, cations (Mg 2+ and Ca 2+ ) can decrease the rate of Cys-induced SeO 3 2− reduction by forming Cys-cations complexes [52]. Moreover, the bioavailability of sulfides influenced Se availability reversely.…”

“…Similarly, the transformation of SeO 3 2− to Se 0 is influenced by the AsA level, which decreases from pH 2.0-5.5 affecting Se uptake by the plants. Moreover, temperature also affects the activation energy to reduce SeO 3 2− to Se 0 [52].…”

“…Селенит может быть восстановлен железом (Fe(0)) [7], аскорбиновой кислотой [8], супервосстановленным кобаламином [9], дитионитом [10], сульфитом [11]. Основным маршрутом восстановления селенита in vivo является его реакция с биологическими тиолами [12][13][14]; недавно доказано образование тиол-S-селенита (RS-SeO2 -) в ходе этой реакции [15]. Однако механизм редокс превращений селенита при его взаимодействии с другими серосодержащими восстановителями изучен недостаточно, а реакции с такими известными и широко применяемыми соединениями, как гидроксиметансульфинат натрия (ГМС, ронгалит, HOCH2SO2Na) и диоксид тиомочевины (ДОТМ, (NH2)2CSO2) [16][17][18][19][20][21], не исследованы вообще (взаимодействие селена с ГМС изучено в работе [22]).…”

“…In this study, strain DW2-9 T was found to be capable of reducing selenite into selenium nanoparticle. It has been reported that low-molecular weight thiols such as glutathione [ 33 ] and cysteine [ 34 ], nitrite reductase [ 35 ], fumarate reductase [ 36 ], glutathione reductase and thioredoxin reductase [ 37 ] could reduce selenite into elemental selenium. In the genome of strain DW2-9 T , all the encoding genes of the respective enzymes mentioned above were found (e.g.…”
