Abstract
Developments in chemical protein synthesis have enabled the generation of tailor-made proteins including incorporation of many types of modifications into proteins, enhancing our ability to control site-specificity of protein posttranslational modifications (PTMs), modify protein backbones and introduce photocrosslinking probes. For PDZ (postsynaptic density protein, disks large, zonula occludens) protein domains, expressed protein ligation (EPL) has been employed to introduce analogs of cognate amino acids, amide-to-ester bond mutations, and phosphorylations in the study of PDZ domain-mediated protein-protein interactions (PPIs). Here, we present protocols for EPL of PDZ domains focusing on phosphorylation and amide-to-ester modifications in the PDZ domain proteins.

Abstract
Glycoproteins have many biological roles. Due to the heterogeneity of natural glycoproteins in the sugar part resulting in glycoforms the evaluation of the biochemical roles of individual glycans remains difficult to investigate. Since pure glycoforms are still not accessible via recombinant or chromatographic methods, the synthesis of proteins with uniform posttranslational modifications using ligation methods or glycan remodeling are currently the best options for accessing these targets. Recent developments in chemical protein synthesis, the assembly of N-glycans and the use of enzymatic procedures have provided access to many glycoproteins with modifications as well as their analogs.

Abstract
The facile rearrangement of "S-acyl isopeptides" to native peptide bonds via S,N-acyl shift is central to the success of native chemical ligation, the widely used approach for protein total synthesis. Proximity-driven amide bond formation via acyl transfer reactions in other contexts has proven generally less effective. Here, we show that under neutral aqueous conditions, "O-acyl isopeptides" derived from hydroxy-asparagine [aspartic acid-β-hydroxamic acid; Asp(β-HA)] rearrange to form native peptide bonds via an O,N-acyl shift. This process constitutes a rare example of an O,N-acyl shift that proceeds rapidly across a medium-size ring (t1/2 ∼ 15 min), and takes place in water with minimal interference from hydrolysis. In contrast to serine/threonine or tyrosine, which form O-acyl isopeptides only by the use of highly activated acyl donors and appropriate protecting groups in organic solvent, Asp(β-HA) is sufficiently reactive to form O-acyl isopeptides by treatment with an unprotected peptide-αthioester, at low mM concentration, in water. These findings were applied to an acyl transfer-based chemical ligation strategy, in which an unprotected N-terminal Asp(β-HA)-peptide and peptide-αthioester react under aqueous conditions to give a ligation product ultimately linked by a native peptide bond.

Abstract
An N-sulfanylethylaminooxybutyramide (SEAoxy) has been developed as a novel thioester equivalent for native chemical ligation. SEAoxy peptide was straightforwardly synthesized by conventional Fmoc solid-phase peptide synthesis without a problem. Moreover, SEAoxy peptide could be directly applied to native chemical ligation owing to the intramolecular N-to-S acyl shift that releases the peptide-thioester in situ. This methodology was successfully applied to the synthesis of two bioactive peptides.

Abstract
A synthetic protocol for the preparation of 162-residue S-monoglycosylated GM2-activator protein (GM2AP) analogues bearing various amino acid substitutions for Thr69 has been developed. The facile incorporation of the replacements into the protein was achieved by means of a one-pot/N-to-C-directed sequential ligation strategy using readily accessible middle N-sulfanylethylanilide (SEAlide) peptides each consisting of seven amino acid residues. A kinetically controlled ligation protocol was successfully applied to the assembly of three peptide segments covering the GM2AP. The native chemical ligation (NCL) reactivities of the SEAlide peptides can be tuned by the presence or absence of phosphate salts. Furthermore, NCL of the alkyl thioester fragment [GM2AP (1-31)] with the N-terminal cysteinyl prolyl thioester [GM2AP (32-67)] proceeded smoothly to yield the 67-residue prolyl thioester, with the prolyl thioester moiety remaining intact. This newly developed strategy enabled the facile synthesis of GM2AP analogues. Thus, we refer to this synthetic protocol as "tailored synthesis" for the construction of a GM2AP library.

Abstract
A practical approach towards N-glycopeptide synthesis using an auxiliary-mediated dual native chemical ligation (NCL) has been developed. The first NCL connects an N-linked glycosyl auxiliary to the thioester side chain of an N-terminal aspartate oligopeptide. This intermediate undergoes a second NCL with a C-terminal thioester oligopeptide. Mild cleavage provides the desired N-glycopeptide.

Abstract
GM2 gangliosidoses are autosomal recessive lysosomal storage diseases (LSDs) caused by mutations in the HEXA, HEXB and GM2A genes, which encode the human lysosomal β-hexosaminidase (Hex) α- and β-subunits, and GM2 activator protein (GM2A), respectively. These diseases are associated with excessive accumulation of GM2 ganglioside (GM2) in the brains of patients with neurological symptoms. Here we established a CHO cell line overexpressing human GM2A, and purified GM2A from the conditioned medium, which was taken up by fibroblasts derived from a patient with GM2A deficiency, and had the therapeutic effects of reducing the GM2 accumulated in fibroblasts when added to the culture medium. We also demonstrated for the first time that recombinant GM2A could enhance the replacement effect of human modified HexB (modB) with GM2-degrading activity, which is composed of homodimeric altered β-subunits containing a partial amino acid sequence of the α-subunit, including the GSEP loop necessary for binding to GM2A, on reduction of the GM2 accumulated in fibroblasts derived from a patient with Tay-Sachs disease, a HexA (αβ heterodimer) deficiency, caused by HEXA mutations. We predicted the same manner of binding of GM2A to the GSEP loop located in the modified HexB β-subunit to that in the native HexA α-subunit on the basis of the x-ray crystal structures. These findings suggest the effectiveness of combinational replacement therapy involving the human modified HexB and GM2A for GM2 gangliosidoses. Purification of recombinant human GM2A proteins by CHO cell line overexpressing GM2A. Reduction of GM2 accumulated in GM2A deficiency fibroblasts by GM2A replacement. Combined effects of modified HexB and GM2A for HexA deficiency fibroblasts. In silico prediction of molecular interaction between modified HexB and GM2A.

Abstract
GM2 gangliosidoses, including Tay-Sachs and Sandhoff diseases, are neurodegenerative lysosomal storage diseases that are caused by deficiency of β-hexosaminidase A, which comprises an αβ heterodimer. There are no effective treatments for these diseases; however, various strategies aimed at restoring β-hexosaminidase A have been explored. Here, we produced a modified human hexosaminidase subunit β (HexB), which we have termed mod2B, composed of homodimeric β subunits that contain amino acid sequences from the α subunit that confer GM2 ganglioside-degrading activity and protease resistance. We also developed fluorescent probes that allow visualization of endocytosis of mod2B via mannose 6-phosphate receptors and delivery of mod2B to lysosomes in GM2 gangliosidosis models. In addition, we applied imaging mass spectrometry to monitor efficacy of this approach in Sandhoff disease model mice. Following i.c.v. administration, mod2B was widely distributed and reduced accumulation of GM2, asialo-GM2, and bis(monoacylglycero)phosphate in brain regions including the hypothalamus, hippocampus, and cerebellum. Moreover, mod2B administration markedly improved motor dysfunction and a prolonged lifespan in Sandhoff disease mice. Together, the results of our study indicate that mod2B has potential for intracerebrospinal fluid enzyme replacement therapy and should be further explored as a gene therapy for GM2 gangliosidoses.
