“…Collagenase activity was not detected in either the tryptone or minimal medium. Purified collagenase showed no caseinolytic activity (Welton & Woods, 1975). It was therefore possible to study the production of alkaline protease activity independently of collagenase production.…”

Regulation of Extracellular Alkaline Protease Activity by Histidine in a Collagenolytic Vibrio alginolyticus Strain

Vibrio alginolyticus synthesized an inducible extracellular collagenase in a peptone medium during the stationary growth phase. These cultures also possessed extracellular alkaline serine protease activity. The alkaline protease activity did not require a specific inducer and it was produced in tryptone or minimal media. The collagenase was not produced in either the tryptone or minimal media. The alkaline protease activity was sensitive to catabolite repression by a number of carbon sources, including glucose, and by amino acids and ammonium ions. Cyclic AMP, dibutyryl cyclic AMP and cyclic GMP did not relieve catabolite repression. Histidine and urocanic acid stimulated the production of alkaline protease activity in tryptone and minimal media. Other compounds associated with the histidine utilization (hut) pathway did not increase alkaline protease activity. Histidine reversed the repression of alkaline protease activity by glucose or (NH,),SO, in minimal medium. Histidine and the compounds associated with the hut pathway inhibited collagenase production.

“…In the presence of collagen or macromolecular fragments of collagen (15), a subculture of this organism (strain 1.029) produces a collagenase having a very high specific activity (12,20). The structural and functional properties of this Achromobacter collagenase (EC 3.4.24.8), as well as the metabolism of strain 1.029, have been described in a series of papers by Woods et al (21,26,27,29,35) and by workers in our laboratory (4, 10,11,13,14,19,30).…”

RICHARD^Strain CIP 82.01 of Vibrio alginolyticus and strain 1.029 (previously designated "Achromobacter iophagus") were compared. Strain 1.029 produces a collagenase of high specific activity (Achrornobacter collagenase; EC 3.4.24.8). Collagenase production is induced in strain CIP 82.01 by collagen or macromolecular fragments of collagen in a manner similar to collagenase induction in strain 1.029; caseinolytic proteinase is constitutive. In this study we demonstrate that both strains also produce a constitutive extracellular endonuclease. Collagenases from both strains cleave either native collagen in its helical region or a similar synthetic peptide; both enzymes are inhibited by ethylenediamine tetraacetate, but not by diisopropyl fluorophosphate. The collagenase subunit (molecular weight, 35,000) of strain CIP 82.01 is similar in amino acid composition to the subunit of the strain 1.029 enzyme, although some of the aspartic and threonine residues in strain CIP 82.01 are replaced by glutamic and serine residues in strain 1.029. Surface radioiodination followed by two-dimensional electrophoresis showed that there are quantitative differences in the major outer membrane proteins of the two strains. Strains CIP 82.01 and 1.029 differ qualitatively in resistance to ampicillin and carbenicillin, in cellobiose fermentation, in ornithine decarboxylase activity, and in halophilism. We propose that strain 1.029, which was originally designated A . iophagus, be included within the species V. alginolyticus, but that this organism be distinguished from other strains of this species by the designation Vibrio alginolyticus chemovar iophagus, with the corresponding collagenase designated "iophagus collagenase" (EC 3.4.24.8).In 1973, Welton and Woods isolated and described the gram-negative aerobic bacterium Achromobacter iophagus (34). In the presence of collagen or macromolecular fragments of collagen (15), a subculture of this organism (strain 1.029) produces a collagenase having a very high specific activity (12,20). The structural and functional properties of this Achromobacter collagenase (EC 3.4.24.8), as well as the metabolism of strain 1.029, have been described in a series of papers by Woods et al. (21,26,27,29,35) and by workers in our laboratory (4,10,11,13,14,19,30).In a recent study (27), which confirmed the original observation of collagenase induction by macromolecular collagen fragments (15), Achromobacter iophagus was reclassified as a strain of Vibrio alginolyticus; however, a direct experimental comparison of strain 1.029 with a welldefined wild-type strain of V . alginolyticus has been lacking. It is well established that the other strains of the Vibrionaceae (23, 31) can be induced (by collagen and fragments of collagen) to produce collagenolytic and gelatinolytic enzymes.We undertook a comparative study to determine the differences between strain 1.029 isolated from a random selection of cured hides in South Africa (34) and a wild-type strain (strain CIP 82.01) of V . alginolyticus from a different ge...
