Kākoʻo ka protein hou i ka hoʻomaʻemaʻe maikaʻi ʻana i ka honua Rare
kumu: mining
I loko o kahi pepa hou i paʻi ʻia ma ka Journal of Biological Chemistry, ua wehewehe nā mea noiʻi ma ETH Zurich i ka loaʻa ʻana o ka lanpepsy, kahi pūmua e hoʻopaʻa pono ai i nā lanthanides - a i ʻole nā ​​​​mea ʻokoʻa honua - a hoʻokaʻawale iā lākou mai nā minerala a me nā metala ʻē aʻe.
Ma muli o ko lākou like me nā ion metala ʻē aʻe, ʻo ka hoʻomaʻemaʻe ʻana o REE mai ke kaiapuni he paʻakikī a hoʻokele waiwai wale nō ma nā wahi liʻiliʻi. No ka ʻike ʻana i kēia, ua hoʻoholo ka poʻe ʻepekema e ʻimi i nā mea olaola me nā kikoʻī paʻa kiʻekiʻe no nā lanthanides ma ke ʻano he mea hiki ke hāʻawi i kahi ala i mua.
ʻO ka hana mua, ʻo ia ka nānā ʻana i nā haʻawina mua e hōʻike ana ua hoʻomohala ke ʻano i nā ʻano protein a i ʻole nā ​​molekole liʻiliʻi e ʻohi i nā lanthanides. Ua ʻike nā hui noiʻi ʻē aʻe he mau huakini, methylotrophs e hoʻololi i ka methane a i ʻole methanol, he mau enzymes e koi ai i nā lanthanides i ko lākou mau wahi hana. Mai ka ʻike mua ʻana i kēia kahua, ʻo ka ʻike a me ke ʻano o nā protein i komo i ka ʻike, ka lawe ʻana, a me ka hoʻohana ʻana i nā lanthanides, ua lilo ia i wahi noiʻi e kū nei.
No ka ʻike ʻana i nā mea hana hou ma ka lanthanome, ua aʻo ʻo Jethro Hemmann lāua ʻo Philipp Keller me nā hoa hana mai D-BIOL a me ka hale hana o Detlef Günther ma D-CHAB, i ka pane lanthanide o ka obligate methylotroph Methylobacillus flagellatus.
Ma ka hoʻohālikelike ʻana i ka proteome o nā cell i ulu i ke alo a me ka loaʻa ʻole o ka lanthanum, ua loaʻa iā lākou kekahi mau protein i pili ʻole i ka hoʻohana ʻana i ka lanthanide.
Ma waena o lākou he protein liʻiliʻi o ka hana ʻike ʻole, i kapa ʻia e ka hui i kēia manawa he lanpepsy. Ua hōʻike ʻia ke ʻano in vitro o ka protein i nā wahi paʻa no nā lanthanides me kahi kikoʻī kiʻekiʻe no ka lanthanum ma luna o ka calcium like kemika.
Hiki i ka Lanpepsy ke hoʻonui i nā lanthanides mai kahi hopena a no laila e paʻa ai i ka hiki ke hoʻomohala i nā kaʻina bioinspired no ka hoʻomaʻemaʻe mau ʻana o nā ʻano honua.
