Assembly of Complex Microtubule Structures01:32

Assembly of Complex Microtubule Structures

2.5K
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

Protein Complex Assembly

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Assembly of Signaling Complexes

6.5K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Sperm Structure and Semen Composition01:22

Sperm Structure and Semen Composition

10.8K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

Structural Isomerism02:34

Structural Isomerism

21.5K
Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Resumen

Introducimos Blocks & Bonds (B&B), un marco de hipergrafos para describir estructuras autoensambladas. Una nueva medida de complejidad composicional se correlaciona fuertemente con el contenido de información, simplificando la evaluación de la complejidad para la materia programable.

Área de la Ciencia:

  • Ciencia de Materiales
  • Química Computacional
  • Teoría de la Información

Sus antecedentes:

  • El autoensamblaje programable es clave para crear estructuras moleculares y cristalinas complejas.
  • La teoría clásica de grafos químicos tiene limitaciones para representar características intrincadas del autoensamblaje.

Objetivo del estudio:

  • Introducir un formalismo generalizado de hipergrafos, Blocks & Bonds (B&B), para describir arquitecturas autoensambladas.
  • Definir y validar nuevas medidas de complejidad estructural y composicional para estos sistemas.

Principales métodos:

  • Desarrollado el formalismo de hipergrafos Blocks & Bonds (B&B).
  • Definido el Código de Estructura (SC) para codificar arquitecturas autoensambladas.
  • Introducidas medidas de complejidad estructural y composicional al estilo de Kolmogorov.
  • Correlacionadas empíricamente las medidas de complejidad en diversos sistemas.

Principales resultados:

  • B&B generaliza la teoría de grafos químicos para incluir interacciones dirigidas, multicolores, simetría y jerarquía.
  • Se encontró una fuerte correlación entre la complejidad estructural basada en tokens y la complejidad composicional más simple.
  • La complejidad composicional es una medida práctica y ampliamente aplicable que rastrea el contenido de información.

Conclusiones:

  • Los hipergrafos B&B ofrecen una representación unificada, escalable y eficiente en información para estructuras autoensambladas.
  • La complejidad composicional proporciona una evaluación computacionalmente accesible pero precisa de la complejidad estructural.
  • El marco admite la clasificación cuantitativa y el diseño inverso de materia programable.
