UniProtKB record for gp37 (P03744)
-
gp37 is the structural subunit of the long tail fiber distal half that recognizes the bacterial receptor.
"Structural component of the distal-half of the long-tail"
-
The distal tip of gp37 interacts with the host lipopolysaccharide receptor and specifies phage host range.
"interacts with the bacterial lipopolysaccharide receptor and specifies"
Deep research review for bacteriophage T4 gene 37 (gp37)
-
gp37 is a virion structural protein forming the distal half of the T4 long tail fiber and providing the receptor-recognizing tip for initial host contact.
"T4 gp37 is a **virion structural protein** that forms the **distal half** of the bacteriophage T4 long tail fiber (LTF) and provides the **receptor-recognizing “foot/tip”** used for initial host contact."
-
The C-terminal needle domain of the gp37 trimer contains multiple His-X-His motifs that coordinate seven iron ions along the central fiber axis.
"A striking feature of the needle is the presence of **multiple His–X–His motifs** coordinating **seven iron ions** along the fiber axis, likely stabilizing the fold and conferring mechanical rigidity needed for adsorption signaling."
