The influence of biotin nutrition on carbon dioxide fixation and malic enzyme formation by Lactobacillus arabinosus.
Biotin has long been impliratcld in a number of carbon dioxide fixation reactions (see Lardy and Peanasky (1) for rcvicw). Two main proposals have been made to explain its mode of action: 1. The vitamin acts as a coenzyme in carbon dioxide fixation reactions. This view was based mainly on observations on the incorporation of radioactivity from C?“oz into compounds in equilibrium with certain su...
متن کاملAmino Acid Nutrition of Lactobacillus Arabinosus
The growth factors required by Lactobacillus arabinosus 17-5 have been studied extensively by Snell and Wright (I), Isbell (2), and Lewis (3). Investigation of the nitrogen requirement has been limited. Hydrolyzed casein has been found to supply the essential nitrogen when supplemented with tryptophane and cystine. Glutamic acid has been found essential (4), and quantitative levels have been de...
متن کاملEstimation of L-malate and fumarate by malic decarboxylase of Lactobacillus arabinosus.
The manometric estimation of L-malate by the malic decarboxylase of Lactobacillu8 arabinosu8 17-5, has been described by Korkes & Ochoa (1948), Ochoa, Salles & Ortiz (1950) and Blanchard, Korkes, del Campillo & Ochoa (1950). As both the bacterial suspensions and the acetone powder extracts used bythese workers have fumarase activity, themethod measures the sum of malate and fumarate. In the pre...
متن کاملGlutamic acid racemase from Lactobacillus arabinosus.
The existence of a glutamic acid racemase activity in Lactobacillus arabinosus has been reported by Narrod and Wood (1) and by Ayengar and Roberts (2). As has been pointed out by Meister (3) these observations with dried cell preparations would not exclude a mechanism for glutamic acid racemization in which alanine racemase is coupled with n-glutamic acid-nalanine transaminase and n-glutamic ac...
متن کاملThe intracellular teichoic acid from Lactobacillus arabinosus 17-5.
It has been shown that extracts of certain bacteria contain both glycerol teichoic acid and ribitol teichoic acid, although the walls of these organisms contain only the ribitol compounds (Armstrong, Baddiley, Buchanan, Carss & Greenberg, 1958). The conclusion that glycerol teichoic acids occur in an unspecified region beneath the wall was substantiated in a more extensive survey (Baddiley & Da...
