ABSTRACT Complementarity-determining regions (CDRs) are antibody loops that make up the antigen binding site. Here, we show that all CDR types have structurally similar loops of different lengths. Based on these findings, we created length-independent canonical classes for the non-H3 CDRs. Our length variable structural clusters show strong sequence patterns suggesting either that they evolved from the same original structure or result from some form of convergence. We find that our length… 
Antibody CDR loops as ensembles in solution vs. canonical clusters from X-ray structures
TLDR
This work reconstructs the kinetics and probabilities of the conformational transitions between canonical clusters, and extends the model of static canonical structures to reveal a dynamic conformational ensemble in solution as a new paradigm in the field of antibody structure design.
SCALOP: sequence-based antibody canonical loop structure annotation
TLDR
SCALOP annotates CDR canonical forms for antibody sequences, supported by an auto-updating database to capture the latest cluster information, and is comparable to that of a standard structural predictor but it is 800 times faster.
Non-H3 CDR template selection in antibody modeling through machine learning
TLDR
A machine learning approach (Gradient Boosting Machine [GBM]) is proposed to learn the structural clusters of non-H3 CDRs from sequence alone and reduces the errors in specific cluster membership misclassifications when the involved clusters have relatively abundant data.
Structurally Mapping Antibody Repertoires
TLDR
The structural annotation of antibodies pipeline is described that maps the outputs of large Ig-seq experiments to known antibody structures and it is found that the majority of sequences coming from such studies can be reliably mapped to an existing structure.
Comparative analysis of the CDR loops of antigen receptors
TLDR
It is found that TCR and antibody CDRs tend to have different length distributions, and where they have similar lengths, they mostly occupy distinct structural spaces, suggesting TCR CDRs are more flexible.
Transitions of CDR-L3 Loop Canonical Cluster Conformations on the Micro-to-Millisecond Timescale
TLDR
The model of static canonical structures is extended to a dynamic conformational ensemble as a new paradigm in the field of antibody structure design to reconstruct the kinetics and probabilities of the transitions between canonical structures.
The H3 loop of antibodies shows unique structural characteristics
TLDR
It is found that over 75% of H3 loops do not have a sub‐Angstrom structural neighbor in the non‐antibody world, which may explain why they are so challenging to model.
Adaption of human antibody λ and κ light chain architectures to CDR repertoires
TLDR
In this work, a diverse set of techniques were employed including machine learning, force field analysis, statistical coupling analysis and mutual information analysis of a non-redundant antibody structure collection and it was revealed how subtle changes between the structures of LCκ and LCλ isotypes increase the diversity of antibodies.
Antibodies exhibit multiple paratope states influencing VH–VL domain orientations
TLDR
The results show that antibodies exist as several interconverting paratope states, each contributing to the antibody’s properties.
Antibody humanization—the Influence of the antibody framework on the CDR-H3 loop ensemble in solution
TLDR
It is observed in the case of the failed humanization that the potentially binding competent murine CDR-H3 loop ensemble in solution shows nearly no kinetical or structural overlap with the superhumanized variant, thus explaining the loss of binding.

The present repertoire has procured an improved image of the current CDR Knowledge-Base, with a novel nesting of conformational sensitivity and specificity that can serve as a systematic framework for improved prediction from sequence as well as a number of future studies that would aid in knowledge-based antibody engineering such as humanisation.
Structural classification of CDR‐H3 revisited: A lesson in antibody modeling
TLDR
The H3‐rules are revised and an improved classification scheme for CDR‐H3 structure modeling is proposed and the concept of “antibody druggability” is discussed, which can be applied as an indicator of antibody evaluation during drug discovery.

PyIgClassify is presented, a database and web server that provides access to assignments of all CDR structures in the PDB to the authors' classification system and is downloadable so that users may filter the data as needed for antibody structure analysis, prediction and design.

The present method, when combined with existing modelling protocols, provides an important addition to the structural prediction of the complementarity determining regions of antibodies.
The structural repertoire of the human V kappa domain.
TLDR
It is shown that the canonical structures selected during the primary response are conserved during affinity maturation: the key residues that determine the conformations of the antigen binding loops are unmutated or undergo conservative mutation.
