Default NMR assignments for the insertion domain of bacteriophage CUS-3 coat protein.

Biomol NMR Assign. 2015 Feb 19;

Abstract
CUS-3 is a P22-like tailed dsDNA bacteriophage that infects Escherichia coli serotype K1. The CUS-3 coat protein, which forms the icosahedral capsid, has a conserved HK97-fold but with a non-conserved accessory domain known as the insertion domain (I-domain). Sequence alignment of the coat proteins from CUS-3 and P22 shows higher sequence similarity for the I-domains (35*%) than for the HK97-cores, suggesting the I-domains play important functional roles. The I-domain of the P22 coat protein, which has an NMR structure comprised of a six-stranded ?-barrel, has been shown to govern the assembly, stability and size of the resulting capsid particles. Here, we report the (1)H, (15)N, and (13)C assignments for the I-domain from the coat protein of bacteriophage CUS-3. The secondary structure and dynamics of the CUS-3 I-domain, predicted from the assigned NMR chemical shifts, agree with those of the P22 I-domain, suggesting the CUS-3 and P22 I-domains may have similar structures and functions in capsid assembly.
