Primary Structure of the a Chain of Panulirus Interruptus Hemocyanin
1986The primary structure of the a chain of Panulirus interruptus hemocyanin (657 residues) has been completed except for one overlap that remains to be proven chemically, and two amide positions, Glx-372 and Asx-405, that are uncertain at this moment.

Kinetic control of co-operativity in the oxygen binding of Panulirus interruptus hemocyanin
Journal of Molecular Biology, 1977Abstract The kinetics of the oxygen reaction of Panulirus interruptus hemocyanin have been studied at pH 9.6 under conditions where the protein exists in the undissociated, co-operative state and in the dissociated, non-co-operative state. Temperature-jump relaxation measurements of the undissociated protein at high oxygen saturation levels show one

Sulfhydryl groups and disulfide bridges in subunit c of Panulirus interruptus hemocyanin
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1989Subunit c of Panulirus interruptus hemocyanin contains, after reduction, three cysteine residues. Determination of sulfhydryls in the native subunit revealed one free SH group. The cysteine-containing peptides were obtained from a pepsin digest. A disulfide bridge was established between Cys 3 and Cys 557 , while Cys 99 bears a free sulfhydryl ...

High‐resolution computed tomography of lobster (Panulirus interruptus) stomach
Journal of Morphology, 2009AbstractWe used micro computed tomography to produce a high‐resolution density image of the lobster (Panulirus interruptus) stomach and identified on this image the previously defined stomach ossicles. These data are the first coordinate‐based, three‐dimensional description of the stomach and are a necessary first step for developing biomechanical ...

The acoustics and acoustic behavior of the California spiny lobster (Panulirus interruptus)
The Journal of the Acoustical Society of America, 2009Numerous animals produce sounds during interactions with potential predators, yet little is known about the acoustics of these sounds, especially in marine environments. California spiny lobsters (Panulirus interruptus) produce pulsatile rasps when interacting with potential predators. They generate sound using frictional structures located at the base

Primary Structure of Subunit B of Panulirus Interruptus Hemocyanin
1986Hemocyanin of the spiny lobster, Panulirus interruptus consists of hexamers of three different subunits, named a, b and c (1). Subunits a and b are the major ones (2). The molecular weights of the three subunits as estimated from SDS-PAA gels are different (2).

Abstract 1. 1. The properties of a class of visual interneurons in the optic nerve of the rock lobster, the so-called seeing fibers (SeF's), were investigated by means of extracellular recording. 2. 2. When repetitively stimulated with a moving or stationary black target the SeF's are strongly habituated, but recover relatively fast when ...

The extent to which individual neural networks can produce phase-constant motor patterns as cycle frequency is altered has not been studied extensively. I investigated this issue in the well-defined, rhythmic pyloric neural network. When pyloric cycle frequency is altered three- to fivefold, pyloric inter-neuronal delays shift by hundreds to thousands ...

Gaffkemia in the California spiny lobster, Panulirus interruptus: Infection and immunization
Aquaculture, 1974Abstract Infection (gaffkemia) can be induced in the California spiny lobster (P. interruptus) with injections of Pediococcus homari (formerly Gaffkya homari ). An LD 5 0 of 10 3 microbes per ml hemolymph is observed at 17°C. Prior immunization of lobsters ( P. interruptus ) with an avirulent strain of P. homari protects lobsters against 100

The temperature dependence of the oxygen binding equilibria and kinetics of Panulirus interruptus hemocyanin has been analyzed within the context of the two-state allosteric model. Oxygenation of the T-state is characterized by a more negative value of DeltaH than that of the R-state; therefore, cooperative effects in oxygen binding to P.
