This entry represents the N-terminal domain of Bacteriophage Mu Gp45 and related proteins from both phages and bacteria. Gp45 is a component of the baseplate that forms a central needle-like spike used to puncture the host cell membrane for tube insertion during virus entry. It serves as the distal plug of tail tube channel and might regulate the process of the phage DNA and protein ejection into the host cell [1,2]. According to structure predictions and comparison, this domain may adopt and OB-fold.	Domain
