چکیده

Bicarbonate stimulates the activities of several class III adenylyl cyclases studied to date. However, we show here that bicarbonate decreased V(max) and substrate affinity in Cya1, a major adenylyl cyclase in the cyanobacterium Synechocystis sp. strain PCC 6803. This indicates that manifestation of the bicarbonate responsiveness is specifically modulated in Cya1.

Phototaxis and impaired motility in adenylyl cyclase and cyclase receptor protein mutants of Synechocystis sp. strain PCC 6803.

We have carefully characterized and reexamined the motility and phototactic responses of Synechocystis sp. adenylyl cyclase (Cya1) and catabolite activator protein (SYCRP1) mutants to different light regimens, glucose, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, and cyclic AMP. We find that contrary to earlier reports, cya1 and sycrp1 mutants are motile and phototactic but are impaired in one part...

Expression of the ggpS gene, involved in osmolyte synthesis in the marine cyanobacterium Synechococcus sp. Strain PCC 7002, revealed regulatory differences between this strain and the freshwater strain Synechocystis sp. Strain PCC 6803.

Synthesis of the osmolyte glucosylglycerol (GG) in the marine cyanobacterium Synechococcus sp. strain PCC 7002 was characterized. The ggpS gene, which encodes the key enzyme (GG-phosphate synthase [GgpS]) in GG biosynthesis, was cloned by using PCR. A 2,030-bp DNA sequence which contained one open reading frame (ORF) was obtained. The protein deduced from this ORF exhibited 85% similarity to th...

Characterization and Partia1 Purification from Chlamydomonas reinhardfii and Synechocysfis

A universal structural feature of chlorophyll molecules is the isocyclic ring. This ring i s formed by the action of the enzyme Mg-protoporphyrin IX monomethyl ester (oxidative) cyclase, which catalyzes a complex reaction in which Mg-protoporphyrin IX monomethyl ester i s converted to divinyl protochlorophyllide (also called Mg-2,4-divinylpheoporphyrin as), with the participation of NADPH and O...

Type II isopentenyl diphosphate isomerase from Synechocystis sp. strain PCC 6803.

Open reading frame sll1556 in the cyanobacterium Synechocystis sp. strain 6803 encodes a putative type II isopentenyl diphosphate (IPP) isomerase. The His(6)-tagged protein was produced in Escherichia coli and purified by Ni(2+) chromatography. The homotetrameric enzyme required NADPH, flavin mononucleotide, and Mg(2+) for activity; K(m)(IPP) was 52 microM, and k(cat)(IPP) was 0.23 s(-1).
