Critique of Carbonic Anhydrase Mechanism Figure

Bilal.bhatti96 provided a mechanism that is difficult to distinguish where the mechanism begins and ends. Also, the arrows are not properly formatted/centered, some of the arrows are illustrated in the wrong direction and some of the bond lengths/angles are distorted. The description is vague and should be written using scientific terminology.

The two edits made by Smokefoot refer to the amount of information provided by Ninja Recs. Smokefoot stated that "Wikipedia is not a school essay. It is a compilation of facts". The comments and edits proposed by Smokefoot are necessary in this article since Ninja Recs provided an unnecessary amount of information that must be more concise. The negative numbers refer to the amount of characters removed by Smokefoot.

Hello,

I hoping to contribute, my knowledge to this article by discussing the strength, covalency and electron transfer effects. Ninja Recs (talk) 01:00, 12 October 2018 (UTC)

You are writing at a level that indicates that your teacher is needed. Please ask your teacher to read some Wikipedia articles first. --Smokefoot (talk) 01:20, 5 December 2018 (UTC)

Ninja Recs's Instructor gave 58 revisions to make to this contribution before moving to the live article however, regrettably, none of them were made --Kcsunshine999 (talk) 22:46, 5 September 2021 (UTC)

Wikipedia "Carbonic anhydrase^[7]" article:

The main purpose of the three edits made by Smokefoot refer to the redundancy of the information added by Bilal.bhatti96. Bilal.bhatti96 provided information that was redundant from the previous version of the article. This indicates that Bilal.bhatti96 possibly did not read the information that was already stated in the article before they made their contribution. Smokefoot proposed necessary edits that removed and reworded unnecessary redundant information from the article. The negative numbers associated with the edits refer to the amount of characters removed by Smokefoot that provide a concise proposition of the material in the article.

The first edit made by Smokefoot on Dec 3, 2018 was a good edit improvement to the introduction for the article since it removes all of the unnecessary information about the history of the enzyme. The second edit made by Smokefoot on Dec 3, 2018 was not a good improvement to the introduction since the edit was not grammatically correct. The edit cannot act as a standalone sentence as it follows improper word association. An edit with a thorough explanation would be required to make the sentence a good improvement.

The edit made by Bilal.bhatti96 on Nov 28, 2019 was a good improvement to the introduction compared to the previous version that was edited on Nov 15,2019. The latest version of the paragraph was added by Bilal.bhatti96 which indicates that the paragraph was a good improvement. The edits that were made are only minor grammatical edits for the major contribution.

Acetylene Hydratase

Introduction

Acetylene hydratase (AH) is used to catalyze the non-redox hydration of acetylene (IUPAC name is ethyne) to form acetaldehyde^[8]. Acetylene inhibits several microbial transformations where it interacts with the active site of the metal-dependent enzymes including hydrogenase and nitrogenase^[8]. This enzyme relies on tungsten as the metal center and is known as the heaviest metal that plays a prominent part in the nitrogen, sulfur and carbon metabolic processes^[9]. Since the activity of AH requires a strong reductant, W(IV) is used as the oxidation state^[8]. Due to the fact that the hydration reaction with the metal doesn't change its oxidation state during the catalysis process reveals that it is a special case and stands out from the other tungstoenzymes^[10]. At the active site, tungsten is coordinated by five sulfur atoms with two pyranopterin (also known as molybdopterin) co-factors along with a cysteine residue^[10]. The site also contains a distorted octahedral geometrical region accompanied by a water molecule as the sixth ligand^[10]. There are several residues that are harbored in the structure of the active site model of AH. The first-shell ligands include two pterin molecules, Cys141 and a water molecule^[9]. The second-shell residues are Asp13, Cys12, Trp179, Arg606, Met140 and Ile142^[9]. The residues coexist to optimize bond lengths, structural formation, and stabilization of the bonds surrounding the metal center^[9]. Asp13 is a catalytically important residue shown in its ionized form^[9]. This residue is important due to its interactions with Trp179, Cys-12-Asp13 and the tungsten water molecule that lower the pKa of Asp13 to keep the residue in its ionized form^[9].
