Caulobacter Bacteriophage Structure

Description

Rendered as a free viral particle, the Caulobacter bacteriophage is presented as an icosahedral capsid with a near-spherical silhouette and a tessellated surface of repeating capsomers. Radially oriented protruding segments project outward from the capsid surface, consistent with exposed receptor-binding domains that sit superficial to the underlying protein lattice. Light green and blue shading accentuates the convex capsid faces and the relief at the intercapsomer boundaries, helping you read depth and symmetry at a glance. No tail elements are shown in this depiction. For Caulobacter phage biology, surface architecture is not academic, it is the interface that determines adsorption and host range. Caulobacter species (classically Caulobacter crescentus) partition into swarmer and stalked cells, and several phages recognize stage-specific outer membrane targets; capsid-proximal attachment proteins and accessory spikes can dictate whether binding occurs at the pole, the stalk, or near the holdfast, and they influence how efficiently a lytic cycle initiates. The repeating capsomer pattern also aligns with how these viruses are interpreted in cryo-EM and capsid assembly models, where symmetry mismatches and local curvature changes often mark sites of genome packaging or vertex specialization. Use this asset in bacteriophage lectures, microbiology lab manuals, and structural virology figures where you need a clear 3D read of capsid topology rather than a schematic head-tail diagram. It also fits grant decks and reviews on phage-host interaction, lytic infection kinetics, and receptor-binding evolution in Caulobacter phage systems.
