Ligands: ANP, EDO, K, MG, TPS Related: 5d9u, 5cm7, 5cc8 Gene: thiL, ABUW_0092 (ACIBA) Activity: Thiamine-phosphate kinase, with EC number 2.7.4.16 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [A0A0D5YC82_ACIBA] Catalyzes the ATP-dependent phosphorylation of thiamine-monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1.[HAMAP-Rule:MF_02128] Publication Abstract from PubMed Thiamine monophosphate kinase (ThiL) catalyzes the last step of thiamine pyrophosphate (TPP) synthesis, the ATP-dependent phosphorylation of thiamine monophosphate (TMP) to thiamine pyrophosphate. We solved the structure of ThiL from the human pathogen A. baumanii in complex with a pair of substrates TMP and a non-hydrolyzable adenosine triphosphate analog, and in complex with a pair of products TPP and adenosine diphosphate. High resolution of the data and anomalous diffraction allows for a detailed description of the binding mode of substrates and products, and their metal environment. The structures further support a previously proposed in-line attack reaction mechanism and show a distinct variability of metal content of the active site.
