Regulatory light chains in myosins. J. Mol . Biol. 104(4): 747-775. 



Regulatory light chains which bind to desensitized scallop myofibrils with 

 high affinity and restore calcium control were found in Mereenaria mereenaria 

 and other molluscan and vertebrate myosins. Although these myosins all have 

 a similar subunit structure and contain about 2 moles of regulatory light 

 chain, only scallop myosin or myofibrils can be desensitized by treatment 

 with EDTA. The regulatory light chains of mollusks restore full calcium 

 binding and also resensitize purified scallop myosin. - J.L.M.

Neural photoreceptors in a lamellibranch mollusc. J. Gen. Physiol. 44(2) : 

 277-299. 



This paper deals primarily with Spisula solidissima, but initially attempts 

 were made also to record impulse activity in siphonal nerves of Venus 

 mereenaria and Mya arenaria. Photoreceptor elements in these 2 species are 

 scattered' through the siphonal wall, and the siphonal nerve and its branches 

 contain numerous afferent fibers from them. Bursts of impulses could be 

 evoked from the entire siphonal nerve or from its peripheral branches when 

 the siphon was illuminated. These impulses were of low amplitude and came 

 from a large number of fibers. They occurred at onset and cessation of 

 stimulus, but there was little sustained activity during prolonged exposure. 

 Fibers mediating this response come from a large number of receptor units, 

 for even fine peripheral branches of the siphonal nerve showed multifiber 

 discharges. On the basis of spike amplitudes the fibers must be much smaller 

 than large motor fibers of the same nerve or the numerous tactile afferents 

 encountered. In Spisula no such multifiber discharges were recorded from 

 siphonal nerve or its branches, but single fiber activity showing light 

 responses was encountered when recordings were made from the central end of 

 the pallial nerve near its point of entry into the visceral ganglion. It has 

 been known for a long time that siphons of lamellibranch mollusks contain 

 photoreceptors which stimulate withdrawal of the siphon on illumination or 

 darkening. - J.L.M.

Effects of temperature on the respiratory metabolism of three Chesapeake Bay 

 bivalves. Chesapeake Sci. 13(1): 1-22. 



Respiratory rates of Maooma balthica, Mulinia lateralis, and Mya arenaria 

 decreased with increasing size and varied directly with temp from 1° to 30°C. 

 High temps (30°) depressed metabolism of cold-acclimated Mulinia and Mya. 

 The only mention of Mereenaria mereenaria is by reference to another paper, 

 abstracted elsewhere in this bibliography. - M.W.S. and J.L.M.
