Nitric oxide (NO), a reactive nitrogen species, is a molecule of high physiological as well as
pathological importance. Physiological mechanisms mediated by NO mainly include …

Ca2+ is a universal signalling molecule involved in regulating cell cycle and fate,
metabolism and structural integrity, motility and volume. Like other cells, red blood cells …

Mammalian nitric oxide synthase (NOS), a flavo-hemoprotein, tightly regulates nitric oxide
(NO) synthesis and thereby its dual biological activities as a key signaling molecule for …

Salt is a major threat to plant growth and crop productivity. Calmodulin (CaM), the most
important multifunctional Ca2+ sensor protein in plants, mediates reactions against …

Nitric oxide synthases belong to a family of dual‐flavin enzymes that transfer electrons from
NAD (P) H to a variety of heme protein acceptors. During catalysis, their FMN subdomain …

Nitric-oxide synthases (NOSs) catalyze the conversion of l-arginine to nitric oxide and
citrulline. There are three NOS isozymes, each with a different physiological role: neuronal …

Calmodulin (CaM) is a cytosolic Ca2+-binding protein that serves as a control element for
many enzymes. It consists of two globular domains, each containing two EF hand pairs …

Nitric oxide synthase (NOS) plays a major role in a number of key physiological and
pathological processes. Knowledge of how this is regulated is important. The small acidic …

Understanding the principles of calmodulin (CaM) activation of target enzymes will help
delineate how this seemingly simple molecule can play such a complex role in transducing …

The intracellular Ca2+ concentration is an important regulator of many cellular functions.
The small acidic protein calmodulin (CaM) serves as a Ca2+ sensor and control element for …
