“…The results of such kinetics analyses are summarized in Table 1. As expected, all tested MCP proteinaceous inhibitors, except for NvCI, inhibit hCPOΔC with K i values in the nanomolar range (PCI 3.2 ± 0.6 nM, LCI 12.8 ± 3.1 nM, TCI 16.7 ± 3.1 nM, and ACI 43.6 ± 6.3 nM), which are comparable to other members of the M14-A subfamily, such as hCPA1, hCPA2, and hCPB (28,33,34,42).…”

“…The activity of MCPs can be specifically regulated by proteinaceous inhibitors (2). During the past 50 y, a number of such MCP inhibitors have been isolated and characterized so far from potato and tomato (PCI and MCPI, respectively) (27)(28)(29)(30), intestinal parasites Ascaris suum and Ascaris lumbricoides (ACI) (31,32), the medical leech Hirudo medicinalis (LCI) (33), ticks Rhipicephalus bursa and Haemaphysalis longicornis (TCI and H1TCI, respectively) (34,35), mammals (latexin) (36,37) and, more recently, from the marine annelid Sabellastarte magnifica (SmCI) (38) and sea snail Nerita versicolor (NvCI) (39). Among them, the latter inhibitor NvCI was found to be the most potent inhibitor discovered for members of the M14-A subfamily, displaying equilibrium dissociation constants in the picomolar range (39).…”

“…A diferencia de las endoproteasas, las metalocarboxipeptidasas solo poseen unos pocos inhibidores peptídicos identificados y caracterizados en diferentes fuentes naturales: en la familia Solanaceae, en tomate (MCPI) y papa (PCI) (Rees andLipscomb 1982, Arolas 2007); en Solanum tuberosum grupo andigenum cv. Imilla morada (imaPCI) (Lufrano D. 2015); en el parásito intestinal Ascaris suum (ACI) (Sanglas 2009); en la sanguijuela medicinal Hirudo medicinalis (LCI) (Reverter 2000); en las garrapatas Rhipicephalus bursa (TCI) (Arolas 2005) y Haemaphysalis longicornis (HITCI) (Gong 2007); Nerita versicolor (NvCI) (Covaleda 2012); en tejidos de rata y humanos (latexina o ECI) (Normant 1995, Pallares 2005; y en el anélido marino Sabellastarte magnifica (SmCI) (Alonso-del-Rivero 2009).…”

“…Se usaron patrones de pI de amplio rango (3,5-9,3) Como se puede apreciar en la Figura 1.12, en este rango de peso molecular (3750-4850 Da) no se observan prácticamente diferencias entre las proteínas que existen en el EC y en los tratamientos térmicos; por lo tanto, podemos decir que las moléculas de este rango de peso molecular, entre las cuales se podría hallar el inhibidor de interés, son estables a los tratamientos con calor. Este dato es muy importante ya que en este rango de pesos moleculares han sido estudiados distintos inhibidores de carboxipeptidasas (Hass, 1981;Lufrano, 2015 Da hasta los 100000 Da., pero en este caso no fue posible encontrar señal en el espectro. Esto se debe a que las proteínas más grandes y pesadas son difíciles de ver en un MALDI-TOF MS debido a su dificultad para ionizarse y posteriormente volar ("time of flight") hacia el detector de señales, lo cual no implica que las proteínas no se encuentren en la muestra.…”
