Assessment of serum homocysteine level and hyperhomocysteinaemia in the northern Persian Gulf

Iranian South Medical Journal, 2007
Background: Homocysteine is a non essential amino acid which is derived from metabolism of the essential amino acid, metionin. It has been shown that an elevated serum homocysteine level in adults is associated with vascular diseases.

The disease‐linked R336C mutation in cystathionine β‐synthase disrupts communication with the PLP cofactor, yet maintains the enzyme's overall structural integrity

The FEBS Journal, EarlyView.
Cystathionine β‐synthase (CBS) is an essential enzyme involved in cysteine metabolism. The mutation R336C, associated with severe homocystinuria and of high incidence in Qatar, reduces its activity. Our research shows that this mutation does not destabilize the enzyme fold but subtly alters the tautomeric equilibrium of the PLP cofactor within the ...

DmdA‐independent lag phase shortening in Phaeobacter inhibens bacteria under stress conditions

The FEBS Journal, EarlyView.
The lag phase is crucial for resuming bacterial growth and can be shortened by fueling the methionine cycle with methyl groups from DMSP or other methylated compounds. While DmdA is the primary DMSP demethylase in Phaeobacter inhibens, stress activates additional enzymes like Bmt. This enzymatic flexibility allows bacteria to exit the lag phase rapidly,

Homocysteine And Recurrent Miscarriage

The Moldovan Medical Journal, 2017
Background: It is known that etiological structure of recurrent miscarriage has genetic, anatomical, infectious and immunological factors; however, the cause of recurrent miscarriage in 50-60% of cases is not completely clear. Homocysteine is a sulfur-containing intermediate product in the normal metabolism of methionine.
