Abstract
Wheat sharp eyespot is a serious disease caused by the phytopathogens Rhizoctonia cerealis and R. solani. Some species in the genus Streptomyces have been identified as potential biocontrol agents against phytopathogens. In this investigation, the physiological, biochemical, phylogenetic, and genomic characteristics of strain HU2014 indicate that it is a novel Streptomyces sp. most closely related to Streptomyces albireticuli. Strain HU2014 exhibited strong antifungal activity against R. cerealis G11 and R. solani YL-3. Ultraperformance liquid chromatography-mass spectrometry on the four extracts from the extracellular filtrate of strain HU2014 identified 10 chemical constituents in the Natural Products Atlas with high match levels (more than 90%). In an antifungal efficiency test on wheat sharp eyespot, two extracts significantly reduced the lesion areas on bean leaves infected by R. solani YL-3. The drenching of wheat in pots with spore suspension of strain HU2014 demonstrated a control efficiency of 65.1% against R. cerealis G11 (compared with 66.9% when treated by a 30% hymexazol aqueous solution). Additionally, in vitro and pot experiments demonstrated that strain HU2014 can produce indoleacetic acid, siderophores, extracellular enzymes, and solubilized phosphate, and it can promote plant growth. We conclude that strain HU2014 could be a valuable microbial resource for growth promotion of wheat and biological control of wheat sharp eyespot.

Abstract
Pseudomonas sp. KM1 produces an amino acid ester hydrolase (KM1AEH) that catalyzes peptide bond formation by acting on carboxylic ester bonds. The KM1AEH gene was cloned from genomic DNA and expressed in Escherichia coli. The recombinant enzyme (rKM1AEH) was purified, and gel filtration showed that it is a 68 kDa monomeric protein. rKM1AEH can synthesize the vasoactive dipeptide tryptophan-histidine from tryptophan methyl ester and histidine as acyl donor and acceptor, respectively. The enzyme showed maximum activity at pH 9.5 and 45 °C and was specifically inhibited by silver (Ag+). Mutation of the catalytic Ser459 residue in the active site of rKM1AEH with Ala, Cys, or Thr eliminated all catalytic activity. The enzyme is a novel ester hydrolase that belongs to the peptidase family S9 based on the phylogenetic analysis.

Abstract
The substrate specificity of aminopeptidases has often been determined against aminoacyl-p-nitroanilide; thus, its specificity toward synthetic peptides and complex substrates remained unclear. The hydrolysis specificity of an aminopeptidase from Bacillus licheniformis SWJS33 (BLAM) was evaluated using a series of synthetic peptides and soybean protein isolate. The aminopeptidase showed high specificity for dipeptides with Leu, Val, Ala, Gly, and Phe at the N-terminus, and the specificity was significantly affected by the nature of the penultimate residue. In the hydrolysis of soy protein isolate, BLAM preferred peptides with Leu, Glu, Gly, and Ala at the N-terminus by free amino acid analysis and preferred peptides with Leu, Ala, Ser, Trp, and Tyr at the N-terminus by UPLC-MS/MS. The introduction of complex substrates provides a deeper understanding of the aminopeptidase's specificity, which can instruct the application of the enzyme in protein hydrolysis.

Abstract
UNLABELLED D-Stereospecific amidohydrolase (DAH) from Streptomyces sp. 82F2, which catalyzes amide bond formation from d-aminoacyl esters and l-amino acids (aminolysis), can be used to synthesize short peptides with a dl-configuration. We found that DAH can use 1,8-diaminooctane and other amino compounds as acyl acceptors in the aminolysis reaction. Low concentrations of 1,8-diaminooctane inhibited acyl-DAH intermediate formation. By contrast, excess 1,8-diaminooctane promoted aminolysis by DAH, producing d-Phe-1,8-diaminooctane via nucleophilic attack of the diamine on enzyme-bound d-Phe. To clarify the mechanism of substrate specificity and amide bond formation by DAH, the crystal structure of the enzyme that binds 1,8-diaminooctane was determined at a resolution of 1.49 Å. Comparison of the DAH crystal structure with those of other members of the S12 peptidase family indicated that the substrate specificity of DAH arises from its active site structure. The 1,8-diaminooctane molecule binds at the entrance of the active site pocket. The electrkon density map showed that another potential 1,8-diaminooctane binding site, probably with lower affinity, is present close to the active site. The enzyme kinetics and structural comparisons suggest that the location of enzyme-bound diamine can explain the inhibition of the acyl-enzyme intermediate formation, although the bound diamine is too far from the active site for aminolysis. Despite difficulty in locating the diamine binding site for aminolysis definitively, we propose that the excess diamine also binds at or near the second binding site to attack the acyl-enzyme intermediate during aminolysis. DATABASE The coordinates and structure factors for d-stereospecific amidohydrolase have been deposited in the Protein Data Bank at the Research Collaboratory for Structural Bioinformatics under code: 3WWX.

Abstract
Pleurotus eryngii serine aminopeptidase that has peptide bond formation activity, redesignated as eryngase, was cloned and expressed. Eryngase has a family S9 peptidase unit in the C-terminal region having a catalytic triad of Ser, Asp, and His. In the phylogenetic relations among the subfamilies of family S9 peptidase (S9A, prolyl oligopeptidase; S9B, dipeptidyl peptidase; S9C, acylaminoacyl peptidase; S9D, glutamyl endopeptidase), eryngase existed alone in the neighbor of S9C subfamily. Mutation of the active site Ser524 of the eryngase with Ala eliminated its catalytic activity. In contrast, S524C mutant maintained low catalytic activity. Investigation of aminolysis activity using l-Phe-NH2 as a substrate showed that S524C mutant exhibited no hydrolysis reaction but synthesized a small amount of l-Phe-l-Phe-NH2 by the catalysis of aminolysis. In contrast, wild-type eryngase hydrolyzed the product of aminolysis l-Phe-l-Phe-NH2. Results show that the S524C mutant preferentially catalyzed aminolysis when on an l-Phe-NH2 substrate.

Abstract
The synthesis of diverse DL-configuration dipeptides in a one-pot reaction was demonstrated by using a function of the aminolysis reaction of a D-stereospecific amidohydrolase from Streptomyces sp., a clan SE, S12 family peptidase categorized as a peptidase with D-stereospecificity. The enzyme was able to use various aminoacyl derivatives, including L-aminoacyl derivatives, as acyl donors and acceptors. Investigations of the specificity of the peptide synthetic activity revealed that the enzyme preferentially used D-aminoacyl derivatives as acyl donors. In contrast, L-amino acids and their derivatives were preferentially used as acyl acceptors. Consequently, the synthesized dipeptides had a DL-configuration when D- and L-aminoacyl derivatives were mixed in a one-pot reaction. This report also describes that the enzyme produced cyclo(D-Pro-L-Arg), a specific inhibitor of family 18 chitinase, with a conversion rate for D-Pro benzyl ester and L-Arg methyl ester to cyclo(D-Pro-L-Arg) of greater than 65%. Furthermore, based on results of cyclo(D-Pro-L-Arg) synthesis, we propose a reaction mechanism for cyclo(D-Pro-L-Arg) production.

Abstract
A new S9 family aminopeptidase derived from the actinobacterial thermophile Acidothermus cellulolyticus was cloned and engineered into a transaminopeptidase by site-directed mutagenesis of catalytic Ser(491) into Cys. The engineered biocatalyst, designated aminolysin-A, can catalyze the formation of peptide bonds to give linear homo-oligopeptides, hetero-dipeptides, and cyclic dipeptides using cost-effective substrates in a one-pot reaction. Aminolysin-A can recognize several C-terminal-modified amino acids, including the l- and d-forms, as acyl donors as well as free amines, including amino acids and puromycin aminonucleoside, as acyl acceptors. The absence of amino acid esters prevents the formation of peptides; therefore, the reaction mechanism involves aminolysis and not a reverse reaction of hydrolysis. The aminolysin system will be a beneficial tool for the preparation of structurally diverse peptide mimetics by a simple approach.

Abstract
X-prolyl dipeptidyl aminopeptidases (X-PDAPs) are useful in various food industries. In this study, we performed sequence-based screening to obtain a stable X-PDAP enzyme from thermophilic Streptomyces strains. We found three genes that encoded X-PDAP from Streptomyces thermoluteus subsp. fuscus NBRC 14270 (14270 X-PDAP), Streptomyces thermocyaneoviolaceus NBRC 14271 (14271 X-PDAP), and Streptomyces thermocoerulescens NBRC 14273, which were subsequently cloned and sequenced. The deduced amino acid sequences of these genes showed high similarity, with ~80% identity with each other. The isolated X-PDAPs and an X-PDAP from Streptomyces coelicolor were expressed in Streptomyces lividans using a hyperexpression vector: pTONA5a. Among these genes, only 14270 and 14271 X-PDAPs caused overexpression and extracellular production without artificial signal peptides. We also characterized the biochemical properties of purified 14271 X-PDAP. In addition, we found that, in peptide synthesis via an aminolysis reaction, this enzyme recognized D-amino acid derivatives as acyl acceptors, similar to L-amino acid derivatives.
