Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Tripeptidyl peptidase (TPP) is an exopeptidase that sequentially hydrolyzes tripeptides from the N-terminus of oligopeptides or polypeptides. We performed screening for isolating novel TPP-producing microorganisms from soil samples. TPP activity was observed in the culture supernatant of Streptomyces herbaricolor TY-21 by using Ala-Ala-Phe-p-nitroanilide (pNA) as the substrate. TPP from the culture supernatant was purified to approximately 790-fold. It was shown to cleave oxidized insulin B-chain, thereby with releasing tripeptide units, but not the N-terminal-protected peptide, Cbz-Ala-Ala-Phe-pNA. The TPP gene, designated tpp, was isolated from a partial genomic DNA library of S. herbaricolor TY-21. The TPP gene consisted of 1488 bp, and encoded a 133-amino acid pre-pro-peptide and a 362-amino acid mature enzyme containing conserved amino acid residues (Asp-36, His-77, and Ser-282) similar to the catalytic residues in subtilisin. TY-21 TPP belonged to the peptidase S8A family in the MEROPS database. The mature TY-21 TPP showed approximately 49% identity with tripeptidyl peptidase subtilisin-like (TPP S) from Streptomyces lividans strain 66.
