Core Idea

Light-oxygen-voltage-sensing domain is treated here as the recurring protein photoreception identity summarized by this source-grounded definition: A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental conditions. A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental conditions. In higher plants, they are used to control phototropism, chloroplast relocation, and stomatal opening, whereas in fungal organisms, they are used for adjusting the circadian temporal organization of the.

Scope of Application

• Chromophore. While the photochemical reactivity of the LOV2 domain has been found to be essential for the activation of the kinase, the in vivo functionality of the LOV1 domain within the protein.

• Documented setting. A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental conditions.

• Documented setting. In higher plants, they are used to control phototropism, chloroplast relocation, and stomatal opening, whereas in fungal organisms, they are used for adjusting the circadian temporal organization of the cells to.

• Chromophore. Common to all LOV proteins is the blue-light sensitive flavin chromophore, which in the signaling state is covalently linked to the protein core via an adjacent cysteine residue.

• Chromophore. In multidomain LOV proteins, formation of this cysteinyl–flavin adduct can trigger conformational changes that propagate to adjacent effector domains, thereby coupling photochemistry to diverse downstream outputs.

Clarity

A clear use of Light-oxygen-voltage-sensing domain names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental conditions.

Manages Complexity

Light-oxygen-voltage-sensing domain compresses multiple protein photoreception details into a stable diagnostic relation. The source shows both the central mechanism—upon blue-light absorption, a covalent bond between the FMN chromophore and an adjacent reactive cysteine residue of the apo-protein is formed in the LOV2 domain.—and the practical consequence—a Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to.

Abstract Reasoning

1. Type the carrier. Identify the protein photoreception entities to which the claim applies.
2. State the relation. Use the source-grounded identity: A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental conditions.
3. Check operation and conditions. This subsequently mediates the activation of the kinase, which induces a signal in the organism through phototropin autophosphorylation.
4. Demand recognition evidence.

Knowledge Transfer

Within the home domain. Knowledge about Light-oxygen-voltage-sensing domain transfers literally when a new case preserves the same carrier type, relation, and recognition test. While the photochemical reactivity of the LOV2 domain has been found to be essential for the activation of the kinase, the in vivo functionality of the LOV1 domain within the protein complex still remains unclear. A Light-oxygen-voltage-sensing domain (LOV domain) is a protein sensor used by a large variety of higher plants, microalgae, fungi and bacteria to sense environmental.

Neighborhood in Abstraction Space

Light-oxygen-voltage-sensing domain sits in a sparse region of the domain-specific corpus (93^rd percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
