Abstract

TTHA1623 is a metallo-beta-lactamase superfamily protein from the extremely thermophilic bacterium Thermus thermophilus HB8. Homologues of TTHA1623 exist in a wide range of bacteria and archaea and one eukaryote, Giardia lamblia, but their function remains unknown. To analyze the structural properties of TTHA1623, the crystal structures of its iron-bound and zinc-bound forms have been determined to 2.8 and 2.2 A resolution, respectively. TTHA1623 possesses an alphabetabetaalpha-fold similar to that of other metallo-beta-lactamase superfamily proteins with glyoxalase II-type metal coordination. However, TTHA1623 exhibits a putative substrate-binding pocket with a unique shape.

摘要

TTHA1623是一种来自嗜热栖热菌HB8的金属β-内酰胺酶超家族蛋白。TTHA1623的同源物存在于多种细菌、古菌以及一种真核生物——蓝氏贾第鞭毛虫中,但其功能仍不清楚。为了分析TTHA1623的结构特性,已分别确定了其铁结合形式和锌结合形式的晶体结构,分辨率分别为2.8 Å和2.2 Å。TTHA1623具有与其他具有乙二醛酶II型金属配位的金属β-内酰胺酶超家族蛋白相似的αβα折叠结构。然而,TTHA1623展现出一个形状独特的假定底物结合口袋。
