CRYSTAL STRUCTURE OF A CAMEL SINGLE-DOMAIN VH ANTIBODY FRAGMENT IN COMPLEX WITH LYSOZYME

Structural highlights

1mel is a 4 chain structure with sequence from Arabian camel and Chick. The April 2011 RCSB PDB Molecule of the Month feature on Nanobodies by David Goodsell is 10.2210/rcsb_pdb/mom_2011_4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	ANTIBODY VH FRAGMENT CAB-LYS3 (Arabian camel), ANTIBODY VH FRAGMENT CAB-LYS3 (CHICK)
Activity:	Lysozyme, with EC number 3.2.1.17
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum

Function

[LYSC_CHICK] Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has bacteriolytic activity against M.luteus.^[1]

Publication Abstract from PubMed

The Camelidae is the only taxonomic family known to possess functional heavy-chain antibodies, lacking light chains. We report here the 2.5 A resolution crystal structure of a camel VH in complex with its antigen, lysozyme. Compared to human and mouse VH domains, there are no major backbone rearrangements in the VH framework. However, the architecture of the region of VH that interacts with a VL in a conventional FV is different from any previously seen. Moreover, the CDR1 region, although in sequence homologous to human CDR1, deviates fundamentally from the canonical structure. Additionally, one half of the CDR3 contacts the VH region which in conventional immunoglobulins interacts with a VL whereas the other half protrudes from the antigen binding site and penetrates deeply into the active site of lysozyme.
