Funkcija[uredi | uredi izvor]

Konjugati proteina glicin-N-aciltransferaze su glicin sa acil-CoA supstratima u mitohondrijama prvenstveno u jetri i bubrezima. Enzim glicin N-aciltransferaza uključen je u detoksikaciju širokog spektra ksenobiotika i endogenih metabolita. To uključuje benzoevu kiselinu, spoj koji se nalazi u voću i povrću i koristi se u medicini i prehrambenim proizvodima kao konzervans; salicilna kiselina, metabolit aspirina i nekoliko endogenih metabolita. Raznolikost se dokazuje širokim rasponom acilglicina koji se izlučuje urinom pacijenata s poremećajima metabolizma organskih kiselina. Još nije opisan nedostatak glicin N-aciltransferaze, ali je pokazano da postoje značajne međuindividualne varijacije u kapacitetu konjugacije glicina. Izoforma a-glicin N-aciltransferaze a je protein od 296 aminokiselina preveden iz prerađene varijante transkripta 1 iRNK. Kodiran je egzonima 2 do 6 transkripta iRNK.^[5]

Molekulska težina[uredi | uredi izvor]

U literaturi se navodi da je molekulska težina ovog spoja približno 30 kDa.^[6] ili približno 27 kDa.^[8] Predviđena veličina je 33,9 KDa. Za goveđi enzim prijavljen je raspon veličina između približno 33 kDa i oko 36 KDa (Nandi, 1979., Vessey, 1992., van der Westhuizen, 2000.). Predviđena veličina goveđeg GLYAT-a, na osnovu njegove sekvence (pristupni broj nm: 177486), je 33,9 kDa. Ovo se dobro slaže s eksperimentalno utvrđenim veličinama.^[8]^[9]^[10]
