Abstract
Biologics are emerging as the most important class of drugs and are used to treat a large variety of pathologies. Most of biologics are proteins administered in large amounts, either by intramuscular injection or by intravenous infusion. Asparaginase is a large tetrameric protein assembly, currently used against acute lymphoblastic leukemia. Here, a gadolinium(III)-DOTA derivative has been conjugated to asparaginase, and its relaxation properties have been investigated to assess its efficiency as a possible theranostic agent. The field-dependent 1H longitudinal relaxation measurements of water solutions of gadolinium(III)-labeled asparaginase indicate a very large increase in the relaxivity of this paramagnetic protein complex with respect to small gadolinium chelates, opening up the possibility of its use as an MRI contrast agent.

Abstract
We report the application of lanthanide-binding tags (LBTs) for two- and three-dimensional X-ray imaging of individual proteins in cells with a sub-15 nm beam. The method combines encoded LBTs, which are tags of minimal size (ca. 15-20 amino acids) affording high-affinity lanthanide ion binding, and X-ray fluorescence microscopy (XFM). This approach enables visualization of LBT-tagged proteins while simultaneously measuring the elemental distribution in cells at a spatial resolution necessary for visualizing cell membranes and eukaryotic subcellular organelles.

Abstract
Complex patterns of protein-protein interactions (PPInts) are involved in almost all cellular processes. This has stimulated the development of a wide range of methods to characterize PPInts in detail. Methods with fluorescence resonance energy transfer can be technically challenging and suffer from several limitations, which could be overcome by switching to luminescence resonance energy transfer (LRET) with lanthanide ions such as Tb3+. With LRET, energy transfer between PPInt partners works over a larger distance and with less topological constraints; moreover, the long-lived luminescence of lanthanides allows one to bypass the short-lived background fluorescence. We have developed a novel LRET method to investigate PPInts between partners expressed as fusion proteins with genetically encoded donor and acceptor moieties. Upon UV excitation of a tryptophan within a lanthanide binding peptide, the Tb3+ luminescence is harnessed to excite either a green or a red fluorescent protein. We demonstrate the usefulness of the LRET assay by applying it to analyze the interactions of the molecular chaperones HSP70 and HSP90 with their common co-chaperone HOP/Sti1. We recapitulate the previously described interaction specificities between the HSP70/HSP90 C-termini and tetratricopeptide repeat domains of HOP/Sti1 and demonstrate the impact of single point mutants on domain-domain interactions.

Abstract
Herein, we establish for the first time the design principles for lanthanide coordination within coiled coils, and the important consequences of binding site translation. By interrogating design requirements and by systematically translating binding site residues, one can influence coiled coil stability and more importantly, the lanthanide coordination chemistry. A 10 Å binding site translation along a coiled coil, transforms a coordinatively saturated Tb(Asp)3(Asn)3 site into one in which three exogenous water molecules are coordinated, and in which the Asn layer is no longer essential for binding, Tb(Asp)3(H2O)3. This has a profound impact on the relaxivity of the analogous Gd(iii) coiled coil, with more than a four-fold increase in the transverse relaxivity (21 to 89 mM-1 s-1), by bringing into play, in addition to the outer sphere mechanism present for all Gd(iii) coiled coils, an inner sphere mechanism. Not only do these findings warrant further investigation for possible exploitation as MRI contrast agents, but understanding the impact of binding site translation on coordination chemistry has important repercussions for metal binding site design, taking us an important step closer to the predictable and truly de novo design of metal binding sites, for new functional applications.

Abstract
Multimodal imaging is a highly desirable biomedical application since it can provide complementary information from each imaging modality. We propose a protein engineering-based strategy for the construction of a bimodal probe for fluorescence and magnetic resonance imaging. A recombinant protein was generated by the fusion of a supercharged green fluorescence protein (GFP36+) with a lanthanide-binding tag (dLBT) that can stably bind two Gd3+ ions. The GFP36+-dLBT fusion protein showed strong fluorescence and exhibited efficient contrast enhancement in magnetic resonance imaging. This protein probe improves the MR relaxation more efficiently than Gd-DTPA (gadopentetate dimeglumine). The superior cell-penetrating activity of GFP36+ allows the efficient cellular uptake of this fusion protein and it can thus be used as a cellular imaging probe. Dual imaging was conducted in vitro and in mice. This result indicates that the fusion of different functional domains is a feasible approach for making multi-modal imaging agents.

Abstract
Consider the lanthanide metals, comprising lanthanum through lutetium. Lanthanides form stable cations with a +3 charge, and these ions exhibit a variety of useful physical properties (long-lifetime luminescence, paramagnetism, anomalous X-ray scattering) that are amenable to studies of biomolecules. The absence of lanthanide ions in living systems means that background signals are generally a nonissue; however, to exploit the advantageous properties it is necessary to engineer a robust lanthanide-binding sequence that can be appended to any macromolecules of interest. To this end, the luminescence produced by tryptophan-sensitized Tb(3+) has been used as a selection marker for peptide sequences that avidly chelate these ions. A combinatorial split-and-pool library that uses two orthogonal linkers-one that is cleaved for selection and one that is cleaved for sequencing and characterization-has been used to develop lanthanide-binding tags (LBTs): peptides of 15-20 amino acids with low-nM affinity for Tb(3+). Further validating the success of this screen, knowledge about LBTs has enabled the introduction of a lanthanide-binding loop in place of one of the four native calcium-binding loops within the protein calcineurin B.

Abstract
![]()
Molecularly
targeted research and diagnostic tools are essential
to advancing understanding and detection of many diseases. Metals
often impart the desired functionality to these tools, and conjugation
of high-affinity chelators to proteins is carried out to enable targeted
delivery of the metal. This approach has been much more effective
with large lanthanide series metals than smaller transition metals.
Because chemical conjugation requires additional processing and purification
steps and yields a heterogeneous mixture of products, inline incorporation
of a peptide tag capable of metal binding is a highly preferable alternative.
Development of a transition metal binding tag would provide opportunity
to greatly expand metal-based analyses. The metal abstraction peptide
(MAP) sequence was genetically engineered into recombinant protein
to generate the claMP Tag. The effects of this tag
on recombinant epidermal growth factor (EGF) protein expression, disulfide
bond formation, tertiary structural integrity, and transition metal
incorporation using nickel were examined to confirm the viability
of utilizing the MAP sequence to generate linker-less metal conjugates.

Abstract
Metalloproteins have long been recognized as key determinants of endogenous contrast in magnetic resonance imaging (MRI) of biological subjects. More recently, both natural and engineered metalloproteins have been harnessed as biotechnological tools to probe gene expression, enzyme activity, and analyte concentrations by MRI. Metalloprotein MRI probes are paramagnetic and function by analogous mechanisms to conventional gadolinium or iron oxide-based MRI contrast agents. Compared with synthetic agents, metalloproteins typically offer worse sensitivity, but the possibilities of using protein engineering and targeted gene expression approaches in conjunction with metalloprotein contrast agents are powerful and sometimes definitive strengths. This review summarizes theoretical and practical aspects of metalloprotein-based contrast agents, and discusses progress in the exploitation of these proteins for molecular imaging applications.
