The High‐Affinity Chymotrypsin Inhibitor Eglin C Poorly Inhibits Human Chymotrypsin‐Like Protease: Gln192 and Lys218 Are Key Determinants

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 93, Issue 2, Page 543-554, February 2025.
ABSTRACT Eglin C, a small protein from the medicinal leech, has been long considered a general high‐affinity inhibitor of chymotrypsins and elastases. Here, we demonstrate that eglin C inhibits human chymotrypsin‐like protease (CTRL) weaker by several orders of magnitude than other chymotrypsins.

A phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824)

open access: yesZoologica Scripta, Volume 54, Issue 1, Page 103-118, January 2025.
Abstract In spite of their important roles in many ecosystems, data regarding population structure and biogeographic patterns of leeches are scarce. To begin to address this knowledge gap, we herein perform a phylogeographic analysis of the North American medicinal leech, Macrobdella decora (Say, 1824). A total of 224 M. decora specimens were collected

Form and function of anguilliform swimming

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2190-2210, December 2024.
ABSTRACT Anguilliform swimmers are long and narrow animals that propel themselves by undulating their bodies. Observations in nature and recent investigations suggest that anguilliform swimming is highly efficient. However, understanding the underlying reasons for the efficiency of this type of locomotion requires interdisciplinary studies spanning ...

Effect of Sulfotyrosine and Negatively Charged Amino Acid of Leech‐Derived Peptides on Binding and Inhibitory Activity Against Thrombin

open access: yesChemBioChem, Volume 25, Issue 3, February 1, 2024.
This study explores hirudins, natural thrombin inhibitors, focusing on the anionic C‐terminal region. Twelve dodecapeptides, derived from various leech species, were synthesized with varying negatively charge amino acid residues and sulfotyrosines.
