Crystal structure of human tRNAHis guanylyltransferase (Thg1)- Native I

Template:ABSTRACT PUBMED 21059936

Function

[THG1_HUMAN] Adds a GMP to the 5'-end of tRNA(His) after transcription and RNase P cleavage. This step is essential for proper recognition of the tRNA and for the fidelity of protein synthesis.[1]

About this Structure

3ote is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
