Lysis

Lysis is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate. In molecular biology, biochemistry, and cell biology laboratories, cell cultures may be subjected to lysis in the process of purifying their components, as in protein purification, DNA extraction, RNA extraction, or in purifying organelles.

Isopeptidase

An isopeptidase is a protease enzyme that hydrolyzes isopeptide bonds, or amide bonds that occur outside the main chain in a polypeptide chain

Piston (subcellular structure)

A piston is a complex contractile organelle found in some dinoflagellates, namely the Erythropsidinium and Greuetodinium genera of the family Warnowiaceae. This group is also well known for possessing other unusually complex subcellular structures such as

HAT transposon

hAT transposons are a superfamily of DNA transposons, or Class II transposable elements, that are common in the genomes of plants, animals, and fungi

Nidoviral papain-like protease

The nidoviral papain-like protease is a papain-like protease protein domain encoded in the genomes of nidoviruses. It is expressed as part of a large polyprotein from the ORF1a gene and has cysteine protease enzymatic activity responsible for proteolytic

Peridinin-chlorophyll-protein complex

The peridinin-chlorophyll-protein complex is a soluble molecular complex consisting of the peridinin-chlorophyll a-protein bound to peridinin, chlorophyll, and lipids. The peridinin molecules absorb light in the blue-green wavelengths and transfer energy

Paired receptors

Paired receptors are pairs or clusters of receptor proteins that bind to extracellular ligands but have opposing activating and inhibitory signaling effects. Traditionally, paired receptors are defined as homologous pairs with similar extracellular

Peter Hausen

Peter Hausen was a German developmental biologist who spent most of his career at the Max Planck Institute for Developmental Biology, where he was appointed Director of the Department of Cell Biology in 1973. Hausen died in 2012

Zinc uptake regulator

The zinc uptake regulator (Zur) gene is a bacterial gene that codes for a transcription factor protein involved in zinc homeostasis. The protein is a member of the ferric uptake regulator family and binds zinc with high affinity. It typically functions as

Phillips Robbins

Phillips Wesley Robbins is a Professor Emeritus in the Department of Molecular and Cell Biology at the Boston University School of Dental Medicine. He moved to BU in 1998 following a career of almost 40 years on the faculty at the Massachusetts Institute
